I'm sure they can. The Gideons, however, provide them free under various circumstances, and there's no real reason to bar them from doing so. It's not like anyone is forced to take one or read one.
If there was such a thing as the Tom Clancy Society, dedicated to putting free Tom Clancy novels in military lodgings so they'd have something interesting to read, I doubt you'd have any major objections... or if it were philosophy texts, or adult education books, etc.
Odd that only the Bible seems to stir such controversy.
