Sure.
Put a starter and a flex plate on it and whirl it over.
Won't tell you much necessarily, since the lifters may or may not have any oil in them, or some might have some and some not.

You can do a compression test like sofaking says, but you can't measure the compression ratio. You'd have to take it apart.
