Logistically I don't think they can. The desk/cabinet thing goes across from the couch for space purposes. Granted a JS has more space (so the bed would fit across from it), but without taking things out of the room and putting them back, moving a bed and sofa bed in those tight quarters would be near impossible.
I am not sure about enchantment since I have never sailed on her, but Serenade had the bed near the slider, but Grandeur had the bed near the door (both regular balcony rooms), so even a regular room might not have the bed where you want it.
