Luffy knows that Shanks is a Yonko, Garp told him (or maybe he was asleep, but I think he was actually listening to that part). But I don't think Law really knows who he is even targeting yet, I think they are gonna end up basically spinning the dial and choosing a Yonko. If it's Shanks, Luffy is going to say no, and any of the other three are fair game. But if it is BB, then he will live to see another day or the plan will fail.
