I would not do that: The only advantage you have by uploading the logo through MediaWiki is that you can easily replace it with a changed version. But how often does that happen? On the other hand you have the danger that one day you come back to your wiki and some jerk has overwritten your logo with some junk, which now comes up on every of your wiki's pages. You could now protec the logo file to prevent that, but also that is only a crutch: In order to make use of your logo you will have to change LocalSettings.php and you will need file system access anyway. But if you have that, then you can also simply upload the image at a safe place, which cannot be manipulated by malicious users so that you don't have to worry about manipulation/defacement of the logo.
