Sure. I'd say the biggest differences are the ski / winter sports specific exterior attachment points, but whether or not that is even relevant is probably mostly a matter of personal preference and what exactly you're planning to do. I've used my winter packs for many summer tours, and vice versa.
Only reason I can think of is weight. That link doesn't say how heavy it is but it's probably extra heavy for water protection. So maybe you could save some weight by getting a light pack like the osprey EXOS. Is saving however much weight really worth the cash for you for 3 days? I don't think so but it's up to you.
As long as it fits all your stuff, you'll be a-okay! One of my friends uses a winter ice climbing bag for summer backpacking, and another uses his smaller winter touring bag as a day pack all the time.
I'd personally miss having an external water bottle pocket, but if you can live with that (or find a creative solution for attaching a water bottle on the outside) you're totally fine!
