It is theoretically possible, because https://services.wikia.com/on-site-notifications/notifications provides these users. You can use the browser extension JustLeafy linked above to view the URL I linked, and under the  property for the upvote notification object should be listed users that upvoted your post.

That's probably confusing for you (and most users), though. I'd like to see somebody make this information viewable through a regular user interface as well.
