No, there is no way withoutout bumping it in the 'active' view (and thus default frontpage). On the good side tag-edits do not make the question reappear in 'hot'.
There is one exception: if a tag in total should be changed (say rename it, merge it into another,...) then moderators can do this.
The standard guideline is: three edits of old questions per day (and user).
(Perhaps I should add that personally I quite appreciate efforts to improve the tagging, and would rather like to see more of it happening.)
