It's possible, but turns out be of very little use. There might be an app somewhere that takes advantage of it, but none of the native apps do.
On the off chance that you do have an app or some other function that you believe will work, you can pair them. Mine is, though it steadfastly refuses to be connected.
You need to make sure both devices have blue tooth turned on and are discoverable. After that, I'm afraid I'm going to get slightly vauge on you.
On the iPad go to Settings >> General >> BlueTooth and make sure it is on.
On the MacBook open Preferences, go to the BlueTooth settings, and make sure it is on and Discoverable.
Now, one of two things worked, and I don't remember which:
Either I saw my Mac show up on the iPad and I initiated the pairing there, or I hit the + sign under the device list on the Mac, saw the iPad, and initiate a pairing there. One of those worked, and I distinctly remember that the other one did not work. You'll have to try both.
As I said before though, I've never actually got them to use the channel for something. Maybe I just haven't tried the right something though, so give it a go and let us know if you discover anything useful.
