In my limited experiance ,yes, you can.
The breeching and lock-up of the Model 94 makes the chambers and barrel shanks all the same.
If you were switching calibers such as from the .30-30 to the .38-55 you would also have to replace the cartridge guides. 30-30 to .32 Special or the other way around is just a barrel swap.
If you have an old rifle remember that ther are changes in the post 64's.
McFarland did a pretty interesting article on barrel switching in an American Rifleman. If I could figure out how to work my scanner....
