I don't think Google approves of this type of content on a site with Adsense, even if you don't show theirs ad on these specific pages.
I see no harm in having adsense on pages that pass adsense TOS, and not have them on pages that do not pass. I've never seen a site banned for such reasons.
My words are not gospel, but based on years of observations and common sense.
