Short answer. No. Section 4 of Rule 10 lets the court summarily correct a defect in the designation of parties and other clearly clerical or typographical errors, at any stage of the action, at its own initiative or on motion, as long as it causes no prejudice to the adverse party.
What the law says
A defect in the designation of the parties and other clearly clerical or typographical errors may be summarily corrected by the court at any stage of the action, at its initiative or on motion, provided no prejudice is caused thereby to the adverse party.

A lighter process for minor errors
Section 4 recognizes that not every defect requires the more formal amendment process. It applies specifically to a defect in the designation of the parties and other clearly clerical or typographical errors. These are precisely the kind of small, non-substantive mistakes — a misspelled name, a transposed number, an obvious typo — that would be disproportionate to require a full motion to amend. A case caption that misstates a party's middle initial or spells a surname slightly wrong is a textbook example: the error is obvious on its face and does not change who the parties actually are.
'Summarily corrected' — a lower bar
For errors of this kind, Section 4 allows the court to summarily correct them, meaning without the more elaborate procedure a substantive amendment might otherwise call for. This correction can happen at any stage of the action, and either at the court's own initiative or on motion of a party — giving both the court and the litigants a fast, low-friction way to fix errors that everyone recognizes are clerical rather than substantive. This authority binds the court in every kind of action where such a defect appears, whether civil or special proceeding, and it is not limited to some early stage of the case — the phrase 'at any stage of the action' means the correction remains available even well into trial or on appeal, as long as the error itself stays a clerical one.
The condition: no prejudice to the other side
This summary process is not unlimited — it is available provided no prejudice is caused thereby to the adverse party. If correcting the defect would actually harm the opposing party's position rather than merely fixing an obvious clerical slip, the summary route under Section 4 is not appropriate, and the matter would need to go through the fuller amendment process instead. A correction that quietly substitutes a different defendant entirely, for instance, is not a clerical fix at all, and dressing it up as one would deprive the adverse party of the notice and opportunity to object that a real amendment would otherwise trigger.
