I had this happen to me recently. Customer came in with a number that had very little coverage, but our carrier had a 1,000 block in the same ratecenter, so we held out some hope. Once we dug into it, the 1,000 block was designated for a different "service offering" with the carrier. They were not offering portability in that Ratecenter, despite having coverage, or even hardware or leased hardware there. So we had to send the customer off. There really were only about 5 carriers serving the Ratecenter, 3 of them wireless, one very local, and our carrier. If your carrier decides not to port a number, even when they seem to be present in the ratecenter in question, they are not required by any law or rule to port, AFAIK. If a company will port in, the other carrier must (IMHO) port out. If not, then you can't port. There may be some subtleties to that, but this is my understanding. Fun!

Assuming the number isn't held by someone exempt from porting, what would prevent someone from being able to port a number from a particular rate center in a LATA they have coverage in?
We picked up a particular carrier for our out-of-area needs and the first thing we throw at them in a LATA we know they have coverage in, they can't do. They have a non-useful reason why. It doesn't appear to have moved to a state where they contacted the losing provider as the response was very fast, so my provider rejected the port, not theirs.
When I started at this company (where we do our own porting), I made sure to port a bunch of numbers from all over our LATA to see what would happen. All successful. That seems to indicate that it doesn't matter which xLEC or tandem currently serves that number, it can move elsewhere.
