I believe that the website should be a valid source for the reasons given by BananaClownMan and Revanvolatrelundar. However, the aforementioned references to Marty McFly, who has been referenced as a fictional character in more than one story, and Arthur Dent, whose mention in "The Christmas Invasion" was more ambiguous as to whether or not he was a fictional character, does give me pause. Making them real people (as opposed to fictional characters) in-universe may be a step too far.

That said, it is worth mentioning that, even if Marty McFly were to be so included, he would not be the first character who is considered both a real person in-universe and a fictional character. For instance, Jean-Luc Picard and numerous other Star Trek characters fall into both categories because of their appearances in Assimilation² and various other references.
