I dont think so. PAPR is a parameter of importance for power
amplifier. That means we are interested in the PAPR of the final
waveform that comes out of your DAC. You will compute PAPR for the
signal that is input to the PA not at any other stage of the
transmitter.

Using RC pulse shaping at the transmitter doesn't imply that you
shouldn't use matched filtering at the receiver. You should perceive
matched filtering as a device that filters the out-of-band noise at
the receiver and applies weights to the samples. You always need
something for this job whatever the pulse shaping filter you use at
the transmitter.
