Not natively with the way StumbleUpon is set up.

What you can do is something old school and it goes a little something like this:

1. Load up two tabs, each with their own StumbleUpon video
2. As you watch one, have the other tab on pause and loading the video into the buffer
3. When you're done with the current tab, hit stumble!
4. Before the next video starts to fully play, hit pause
5. Go to the other tab.
6. Flip back and forth between the tabs, loading and pausing as you do.
