It all comes down to how much risk you wish to take.
You can book a legal connection in IAH of 30 minutes. But I wouldn't do it.
You can show up to board a flight seven minutes before scheduled departure and most of time you will board the flight. But UA has the right to deny you boarding if it is less than 15 minutes.
You can check your bag through TPE to HKG with two tickets. There is probably a 1 in 30 chance that your bag will be lost and if it does, you will have a lot of problems. If it doesn't get lost, then everything is fine.
Flying nowadays is lots of shades of gray.
