No. SERPENT is not part of the standard OpenPGP cipher profile, and
GnuPG implements the OpenPGP specification quite closely.

GnuPG extends this with support for Camellia-128, Camellia-192 and
Camellia-256. I don't know the reasoning for introducing Camellia, but
I'm sure there's a solid basis for it.
The best way to get GnuPG to support SERPENT is to convince the IETF
OpenPGP Working Group to add SERPENT to the symmetric cipher profiles.
