Its context
Yes. Well written questions are sentences. If you are talking about using the words all by themselves, then context comes into play. I would argue that, without any context at all, this: 'Who?' is not a question. But in context like this: John said "Someone brought a casserole to share with us for lunch." "Who?" Mary replied. I would argue that the predicate is understood, and 'who' is a sentence.
