Well, maybe not. SCP canon is whatever you want it to be, after all. But the author's headcanon is that they're unrelated, and the fact that they both have seven seals is because that's a common trope when dealing with such things.
SCP-2317 is meant to make you think of SCP-231, but only insofar as it is thematically appropriate. Fear of the unknown versus fear of the horrible truth, and all that.
