2.4 wireless receivers

Today I purchased the Microsoft Arc Touch Mouse. It works well, and so far I think its pretty cool. I was going to hold out for the launch of The Microsoft Touch Mouse, but decided to give this a try. At my desk I use the Wireless Laser Desk 6000. I got that set up a couple of years ago, so it has a large bulky USB wireless receiver. The touch mouse came with a nano receiver, so I was wondering if the keyboard would be able to use the new receiver as well?

(I hope this is the right forum to ask)

Thank you.

EDIT:Messed up spelling receiver in title sorry.
