Short answer. No. A guarantor may bind himself for less than the principal debtor but never for more, whether in amount or in how burdensome the conditions are. If a guaranty is written to exceed what the debtor owes, the Civil Code automatically cuts it back down to the debtor's own obligation.
What the law says
A guarantor may bind himself for less, but not for more than the principal debtor, both as regards the amount and the onerous nature of the conditions.

A guaranty rides on top of the debt, never above it
Article 2054 fixes the ceiling on what a guarantor can be made to answer for: he may bind himself for less, but not for more than the principal debtor. A guaranty is an accessory obligation — it exists to secure someone else's debt, not to create a bigger one. The ceiling covers two things at once: the amount the guarantor can be held to, and the onerous nature of the conditions, so a guaranty cannot impose harsher terms than the principal obligation carries even if the peso figures happen to match.
What happens if the guaranty is written to exceed it
The article does not simply forbid an excessive guaranty — it fixes what happens when one is signed anyway. Where a guarantor has bound himself for more, the law does not void the guaranty; it automatically reduces the guarantor's obligation to the limits of that of the debtor. In other words, an overreaching guaranty is not thrown out, it is trimmed down to size, and the excess simply does not bind the guarantor regardless of what the document says.
What this means if you are being asked to pay
If a creditor is demanding an amount from you as guarantor that is higher than what the principal debtor actually owes, or on terms harsher than the debtor's own obligation carries, that demand runs past what Article 2054 allows. Compare the figure being asked of you against the debtor's real, current obligation — interest, penalties, and any partial payments already made all affect what that figure should be — before assuming the guaranty document's face amount is what actually binds you.
The reduction is automatic, but proving it is on you
Article 2054 does the trimming by operation of law, so a guarantor does not need a separate agreement or a court order changing the guaranty's wording before the lower ceiling applies. What you still need, in practice, is evidence of the debtor's actual obligation — the loan documents, statement of account, and any record of payments the debtor already made — because a creditor collecting on the guaranty will simply present the guaranty's face figure unless you show what the debtor really owes. Keep that evidence before disputing any demand that looks inflated.
