Well The Black Dragons are not the only chapter that is suspected of taint because all of the chapters that are formed from the cursed founding are all flawed to a degree.

And if the act of allying yourself with the alien means that you are tainted then the inqusition will have to investigate a lot of chapters including the Blood Angels and the Ultramarines as well

Really the Imperium can't afford to take one chapter off the frontlines not least dozens for alleged offences
