No you cannot. Wikis created using FANDOM/Wikia/Gamepedia must be open to the public for both viewing and editing. If you wish to make a private wiki, there are some other MediaWiki-based hosts out there that you can consider. Your options broaden even more if you are not committed to using the MediaWiki platform. Among the various other options for MediaWiki, I would suggest taking a look at Miraheze and ShoutWiki.
