I can't really say. I know you can (for example) use LispWorks to write CL for mobile, targeting both - Android and iOS, but I think there would be greater friction to keep it cross-platform, each platform's nuances would have to be handled differently, it's not going to be very unified codebase (I think).
Isn't CL better for this? You are not bound to some VM and you can produce native binaries.
