Sure. Both answers are correct; it's a matter of how David and I are
interpreting your question.

David is talking about using classic PGP 2.6-style ClassicPGP keys to
encrypt OpenPGP traffic. This answer is correct. You can use
ClassicPGP keys in an OpenPGP environment if both parties are using a
newer version of GnuPG/PGP.

I'm talking about using classic PGP 2.6-style ClassicPGP keys to encrypt
ClassicPGP traffic. AFAIK, this answer is correct; GnuPG was never
meant to be a conformant ClassicPGP application. (It's possible that
things have changed in the GnuPG codebase since the last time I looked
at this, though.)
The short version is that David read your message as "can GnuPG be used
to process OpenPGP traffic while using ClassicPGP keys", and I read it
as "can GnuPG be used to process ClassicPGP traffic, using ClassicPGP keys".
