Yes, they can. As any other MI, it depends on the person: just because you have BPD doesn't mean you will also have DID. They might be co-morbid, yes, but it doesn't mean anything. I have them, yet I've met lots of other people in this forum that don't.
If your thoughts don't present individuality, a name, a voice, talk to you in a different voice or anything that makes them anything more than a thought, then I wouldn't classify them as an alter.
Regarding your other question, I'd say that more than being a BPD trait, those are intrusive thoughts of anti-social tendencies. You can spot some tendencies and classify them as "BPD traits", but there's not even one existant tendency you can single out and call "BPD" as an entire entity or thing.
I have 4 dissorders and somehow I'm more of a normal human than everyone else.
