If you mean 'certificate' as a whole, this isn't possible, as the expiration
date is part of the certificate. If you really mean make a new certificate
with the same public key that has a new expiration date, that is possible,
but is normally a bad thing to do.

You might not be able to easily do this. In theory it should be possible
becausse you still have the private key and can self sign a new certificate
with a modified expiration date.
