Crete_Armenoi is post-Mycenean according to Lazaridis, right? The Dorian invasion marks the end of the Mycenean era. So it can be associated with Dorians. The thing is that we don't have more specimens. But we have 1 out of 1 post -Mycenean specimen and it differs from Myceneans because it has more northern ancestry. This does give some hints. Moreover, the specimen is from Crete. Who knows what would have wandered around in parts of Thessaly/Epirus by that time? We'll just have to wait and see.
Well, if I am not mistaken, the sample is around 1340, so definitely preDorian period. The so called "Dorian invasion" (I would suggest that there is just a movement from the periphery of the Mycenaean world to the centers, of some other Greek-speaking people - many would agree) is dated not before 1200 and in Crete they put it even a bit later.
Not to mention again the low quality of the sample and the fact that was a woman.
In any case, we wait and see.
