Any problem.

But:

a) If your unit is a Brain1, avoid to power the Arduino nano from the 3,3V of the GOV connector, use only the common/gnd and the signal of the GOV connector and power the Arduino nano from servo rail voltage (with a voltage regulator if needed for Arduino nano).

b) May be is not needed but if possible, avoid to change the impedance of the signal adding pull up or pull down resistor (also in the programmation setup of the port used from Arduino nano).

To understand if RPM signal is received or not received from the GOV port of Brain is simple: look at the end of the governor page (wizard and/or advanced) and look if RPM value stay at zero or change changing the motor RPM.
