I want to just pop up and say that, in my mind, separate K9 articles make more sense. This is for the simple reason that K9 Mark I left and so Mark II was created. He left and Mark III was created (for SJA). They're separate units. What makes it confusing is K9 Mark 2.

From memory, in the episode Regeneration, K9 Mark I appears from a battle and "dies". Its heavily suggested that he's escaped the Time War but is never stated on-screen. He then "regenerates" into K9 Mark 2. So, you could argue that if we're combining articles that K9 Mark I and 2 have the same article. And, if we're saying that the rebuilt K9 Mark III in the SJA is now K9 Mark IV, then they get the same article.

So in conclusion... I don't know haha. We've evidently got K9 Mark I/2, K9 Mark II, and K9 Mark III/IV. They're not same... yet a couple of them are. It's complicated.
