But that is defined in the same file as the unload-function...

You want to write the same code, but put it in define-minor-mode. I
don't think define-minor-mode should worry itself with unloading.

I do not say that there are not, I say that they are not easy to
generalize. Some are. For example, removing a minor-mode for the
minor-modes menu seems a good idea, and should be done by
unload-feature if it is not done already, because calling a
nonexistent function is an error.
