Why not (out of interest)?
I carried a laptop (this laptop in fact) all the way from Lands End to John O'Groats in a pannier. It stayed in a soft bag and then another waterproof stuff bag - you can see the bags in the picture. I slotted it in into the sieve in the pannier and I had no problem.
It probably helped that it's an 'ultrabook' and very small. Having an SSD rather than hard disk may also make it more robust.
Here's when I stopped off just north of Inverness to take a call (I was technically working when I made the trip)
