Since "Z" doesn't apply to business loans, this wouldn't be an issue unless your consumer customer could see it and be confused, believing it did apply to what they were looking for. Linked and labeled properly this shouldn't be a problem.
I would also refer you to the
FTC site on advertising practices for reference.
I would also suggest reviewing your pages on your PC instead of, or in addition to the printed pages. You want to test those links and ensure they are going where you expect them to, so you can see animated GIFs and banner ads, etc.
