If board have high speed design it is very unlikely that you can do it
properly (because you have to be careful about routing to ground, you have
many lines that you have to match etc etc and when you have only 2 layers
it is difficult to keep it all correct). In theory maybe it could be
possible but it is a hell of a work and then you risk a lot that PCB will
not be good.
