edit in question i only said i didn't think we're allowed to do it but i can't cite a policy or guideline on it the main reason tho would be that it isn't a content page but a talk page it should either go on the main page or in a separate page tags can link to talk pages for discussions on moves and such but i've never seen an link in the text to contnet placed on the talk page i'm going to ask a few admins and see if they know of a guideline or policy explicitly forbidding it
