No and Yes.

No, you can't remove a class. Yes, you could define a class depending
on another class. We do this in 50-host-classes:

(ifclass I386 || ifclass AMD64) && echo GRUB 

But I always recommend to let classes be a simple ordered list. If you
start a hierachy of classes with a sort of inheritance, you will lost
the overview and will not understand which classes will influence
which part of the intsallation.

KISS: Keep it simple and stupid!
