Short answer. Almost certainly yes — a misspelled name is the statute's own example of a clerical or typographical error. It still has to be harmless, obvious on the face of the record, and correctable by reference to other existing records, but those three tests are exactly what an ordinary misspelling satisfies.

What the law says

a mistake committed in the performance of clerical work in writing, copying, transcribing or typing an entry in the civil register that is harmless and innocuous, such as misspelled name or misspelled place of birth or the like, which is visible to the eyes or obvious to the understanding, and can be corrected or changed only by reference to other existing record or records

Three tests, all in one sentence

A clerical or typographical error is a mistake committed in the performance of clerical work in writing, copying, transcribing or typing an entry in the civil register that is harmless and innocuous, such as misspelled name or misspelled place of birth or the like, which is visible to the eyes or obvious to the understanding, and can be corrected or changed only by reference to other existing record or records. The error must have arisen in clerical work; it must be harmless and apparent; and other records must be capable of showing what it should have said. A name typed with a transposed letter meets all three without argument.

Correcting a spelling is not the same as changing a name

The line the registrar will hold is between fixing how a name was written and substituting a different one. Restoring an obviously dropped letter is a correction. Replacing the name recorded at birth with the name you have always been called is a change of first name, which the same law also allows administratively but on separate grounds and as a distinct kind of petition. The distinction matters because "First name" refers to a name or nickname given to a person which may consist of one or more names in addition to the middle and last names. The change-of-name route reaches the first name only, not the middle or last.

A surname is the harder case

A misspelled surname can still be a clerical error — the definition speaks of a misspelled name without confining it to the first — but registrars look at it more closely, because a surname carries filiation and a change to it can shift who a person's family is. That is the boundary the same section polices with its proviso: no correction may involve a change of the petitioner's nationality, age, status or sex. If what you are really seeking is a different surname rather than the correct spelling of the one recorded, expect the administrative route to close and the judicial one to open.

What to bring

Because the definition requires the error to be correctable by reference to other existing records, the documents are the case. Section 5 asks for a certified true machine copy of the certificate or of the registry page containing the entry, and at least two public or private documents showing the correct entry — school records, baptismal or membership records, employment or government-issued records, anything predating the dispute. Assemble those two first. A petition supported by documents that themselves carry the misspelling proves the opposite of what it needs to prove, and that is the most common reason a straightforward correction stalls.

One amendment to check before you file

Republic Act No. 10172 (2012) amended this Act after the text quoted above was enacted, extending the same administrative route to the day and month of the date of birth and to the sex entry, and setting additional requirements for petitions of that kind. A misspelling is not affected by it. But if what you actually want corrected is a birth date or the sex entry, treat the procedure described above as a starting point only and check the amended provisions first.
