With the usual caveats about headspace and the possible need for some fitting, the answer is yes.
One thing, though. All reports are that the 2A rifle was made with better steel than the SMLE, and that would apply to the bolt as well as the receiver, so you should keep a close check on headspace if you make a swap like that, as the lugs might batter more than they would with the right bolt.
I also advise not using commercial .308 ammo in that rifle; stick to 7.62 NATO specs.
