FWIW, I'm not an expert on this so take what I say with a grain of salt.
An anchor tag that links to another page but looks like a button is probably fine. So long as you can access them via the keyboard (tabbing to it) and they have a distinct appearance when focused so if you are tabbing through you can see whats active (this is different from the hover attribute).
