I have a 3.3v board, and an RF transmitter that can handle up to ~12v. Assuming I want to power the transmitter with 12V for the range but use the 3.3v signal coming from the board's IO for data, can an optocoupler be used to run these two devices? Can it keep up with whatever the data is like for 4…

Yes - but a simple transistor would do quite as well
