You can try; it's possible the airlines' automated systems that verify that the name matches ignores the first name, since it would be too complicated to program the system to be aware of things like nicknames, middle initials, or other possible permutations.
However, given the surcharges charged for earning miles on rental cars, I'd certainly check first with a single test rental before going whole-hog and booking a bunch of cars...
