Can the same TIN exist for both an SSN and an EIN?

Question

In the US, is it possible for the same 9 digits to exist as a valid SSN, and also as a valid EIN?
For example, Person One is 123-45-6789, and Business Two, Inc is 12-3456789.

Apparently, it can happen.
On Reddit’s r/personalfinance subreddit, a user posted their story about this happening to them:
My SSN has the same integers as someone's EIN
A couple of people in the comments also claimed to have discovered this firsthand as well.
