[uBITX] Key line resistor: OK to mount on Raduino board?

K5DH
 

There is a 4700 Ohm pullup resistor that must be installed between +5 V and the key line.  The wiring instructions show it being installed at the key jack.  Is it OK to install it on the Raduino board, on the solder side of the Digital connector?  Or is soldering to that board too risky?
