Technically, when speaking about a specific language version of Wikipedia (i.e. en.wikipedia, ja.wikipedia, etc.), it's appropriate to call it "the [lang] Wikipedia" or even "a Wikipedia (project)", while keeping it a proper noun.

Further, a wiki is a site that anyone can edit, really. It doesn't have to use MediaWiki. TV Tropes uses PmWiki and it's a wiki. Wikipedia was still a wiki before it transitioned from UseMod to MediaWiki, which was created to serve its needs. There's plenty of wiki software; MediaWiki is but one software. All MediaWiki-run sites are technically wikis, but not all wikis are technically MediaWiki.
