In some situations yes, in others no.

Camlp4o is supposed to parse all OCaml plus things such as stream
parsers. Since adding keywords ("parser", for instance) may break
legal OCaml programs, Camlp4o is supposed to parse OCaml programs that
don't conflict with such extensions. Camlp4o cannot therefore parse
_all_ OCaml programs.

I'm not sure I understand your question, but the OCaml and Camlp4o
parsers use a different technology. The latter is extensible while the
former is not.
