I don't think so, they're not going to redesign a chassis for 3 door and 5 door models specifically just to have different leg room. The front seats in a 3 door car might slide back and forth with a greater sliding distance but there wouldn't be any difference besides for that (other than the width which Corey mentioned).

I'm not going to fuel the debate any further but hot hatch = 3 door 5 door has just been brought into the market to help sales and make things easier for the nuclear family (2.5 kids).
