No, if you soul trapped him he would remain inside the soul gem until it was used. When it was used his soul would then either have just enough power to unbind itself from the enchantment and make it to the soulcairn, Get half way and end up as a restless spirit (a ghost) or be completely destroyed in the process. Another way people end up in the soul cairn is not revering (binding yourself to) a deity. This is why people who stay true to the way of nords end up in sovngarde, why people who stay true to the way of the redguards end up in the territories of Yokudan gods (which may just be differently named deities of skyrim) and why daedric cultists end up in their masters realm.
