Here's what I got from a quick prose search:
 * "This [ 1973 ] is an era that hasn't even heard of Princess Diana yet." (PROSE: Verdigris)
 * Ian doesn't recognise Diana's name in a magazine, while Vicki laughs at his ignorance in PROSE: Every Day.
 * "This [Spiritualist] church had a less than orthodox iconography, come to think of it. They were very fond of the Virgin Mary but also, it seemed, of Princess Diana." (PROSE: The Blue Angel)
 * [The Eighth Doctor says,] "I mean you wouldn't expect Queen Victoria and Princess Diana to necessarily hit it off right away. There's always a bit of a generation gap, even with royalty.' 'Royalty?' Fitz asked. And who the hell was Princess Diana? he wondered." (PROSE: The Taking of Planet 5)

That's all I can find from my collection. So no description or full name or anything, but lots of people who've never heard of her.
