Can you get away with.......

Can you get away with running a washing machine waste into a 32mm waste pipe, with maybe a 600mm plus drop before going along the wall to outside? Also a condensate pipe would be connected on at somepoint

Probably get away with it depending on length but better to redo in 40mm to do it right.

Whats the reason not to do it in 40mm, convenience?

pretty much, but your right 40mm
