My Spektrum receiver has handled 5s lipo before without issues (well, sort of). I had a BEC blow and sent full 5s battery voltage to the rx and servo. The servo fried which pulled enough current to blow the PCB traces in the rx (between the power/ground pins). I bridged all the power and ground pins via a wire to replace what was blown and it's still working fine ever since.
IIRC, I was snooping around inside the Rx and there was a small linear regulator between the power pins and the actual receiver circuitry. I don't know if I'd run that high voltage for very long, but it apparently is possible.
