Yes, the SE has a different straight stitch plate (and different, quick-set bobbin area - kind of hard to describe that one). Those are the main differences between the two and you can't simply use the SE plates on the non SE machine.
(ETA - I have to check, but I think there might be a 3rd needle plate with the SE as well)
