That's not something we'd recommend - PDFs can have security concerns for users who download it from the wiki. In addition, they usually don't contain anything that you couldn't put on an article page (text, images, tables), but there, others can edit and improve the content further, while a PDF is always static.

Yet another reason is that it's harder for us to control the content uploaded via PDFs, so we couldn't guarantee a PDF's content doesn't violate our terms of use. Maybe you can find another way to add that information to the wiki?
