I don't think this is slang. Phrasal verbs is the posh term. In this case, the two-word phrasal verb "put up" (accommodate) is different from the three-word "put up with" (tolerate). One question is whether the the final word is really a preposition or an adverb. If you can separate the main verb from the other bit (We put my mother-in-law up in the attic.) suggests it is an adverb. If separating the words sounds weird (We couldn't put up with my mother-in-law's moaning.), it's probably a preposition.
Therefore, saying, "We could put Churchill up." is fine.
