You seem to be under the impression that Z exists as a character outside of the events portrayed in Film Z. He doesn't. The fact that he lost his arm to someone that was later made Shichibukai has nothing to do with the canon storyline because he isn't /in/ the canon storyline, at all. Oda creating a character doesn't automatically make that character "real." Saying Z is a real character would be saying that Bear King, Gasparde, and Musshuru are real characters.
