I am afraid there is no a clean way to purge empty tags. I don't want to recommend you the way with removing old directory using TIFFUnlinkDirectory() because it involves rewriting the whole data chunk including strip/tile arrays. You can add an entry to our Bugzilla requesting the function for field dropping.
