Example: -er words. You can rhyme "teacher" with "reacher", but not with "plumber", even though all three have the same endings, technically.
Why that is, I do not know.

Sure you can; e.g. you can get away with matching "teacher" with "catcher".
My good old sixth grade teacher
Though not always eye to eye
Introduced me to the Catcher
You know, In The RyeThere is a kind of assonance (or whatever) in English where the stressed one can differ. The juxtaposition of such words or endings can sound good. For instance "pitter-patter". This can be exploited to create a near rhyme, like my teacher and catcher verse.
Moreover, if it is the unstressed one that doesn't match, that is no longer the case. We cannot rhyme "teacher" with "teapot" as line endings.
The Wikipedia page:
https://en.wikipedia.org/wiki/Perfect_and_imperfect_rhymes
states the same conditions you have given for perfect rhyme: stressed vowel and following unstressed, if any, are a match. Then it goes into the exceptions.
Maybe in some $15,000 per year kindergarten in Beverly Hills; there is no such rule elsewhere.
