We could distinguish "time zone" in the usual English-language sense (a set of geographic locations that currently share the same standard time offset from UTC) from "timezone" in the POSIX sense (a history and predicted future of UTC offsets, abbreviations and isdst flags). If so, the tzdb documentation could be more careful about using "time zone" for the former and "timezone" for the latter, and this would make for fewer changes to the GNU/Linux man-pages for tzdb. I can look into this and propose an updated set of tzdb-related patches accordingly.
I've done that, plus a few other minor fixups, and have installed the attached proposed patches into the development tzdb repository on GitHub. I plan to follow up by emailing to linux-man a corresponding set of patches to the GNU/Linux man pages.
