Can I put a 2013 RDX awd into a 2010 rdx

Make ALL of the 2010 operating systems and drive train identical to the 2013. Good luck!!

You'd be better off keeping the 2013. The transfer case will not mate to the transmission. The AWD transmission will not mate to the 2.3 engine. You could custom build an adapter plate but that would not be cheap. Anything can be done for the right price. I'd figure upwards of $10,000. How bad do you want it?
