My understanding is that AC compressors that handle R12 can handle R134a because these two refrigerants work in similar pressure ranges (vs R410 which operates at a much higher pressure range). However, the required lubricant oil can be different for different compressors.
As R12 refrigerant has been gradually phased out since 1992 and onwards, the cost to buy R12 is becoming more and more expensive over the years. To the point now R12 is so rare and expensive, its no longer economical to continue using R12. So more and more people choose to use the 134a to replace R12.
I believe most older R12 systems, if not all, can be retrofitted to use r134a. The conversion process seems just to replace the port adapters.
I had a trailer that was built in the '80s and it has an old air condition system that uses R12. When I called for a mobile service for repair, they said the refrigerant was empty, so they just refilled it with R135a. It seems just works fine.
