My guess is that it should fit with even with a bit of padding. The hardware sticks into the bags a bit on the rack side of the back rollers (at least the classics) and you want to somehow insulate your laptop from this.
Anthony691 is correct. I have the Classic Back Rollers, and my wife has the Packer Plus rear panniers. Both have hardware on the inside that left imprints on the neoprene sleeve we use for our netbook. She usually carries it , and just pads it with clothing. Our netbook does have a solid state hard drive so I'm not very finicky with it.
You should have plenty of room in your Back Rollers for a notebook. While my "full" sized laptop is on the small size there is plenty of room for it. However, since we got the netbook room it is not an issue for me- my wife carries it!
