To my knowledge, you need to be an admin to move pages into the Template namespace. Also, I don't recall any criterion other than the template having some use, rather than one that will only sit there taking up space.

In this case, it seems to be a valid template with many uses. Though, for use inside things such as Infoboxes, I would definitely recommend using the   tags, so that the template-within-template bug of only opening a page in the source editor will not occur. (This is catering for those users that do use the visual editor, as well as the ones who use the source.)

If you'd like the code moved, I can do so.
