I do not remember learning about such warning. I went through MCDU messages list [DSC-22_20-50-20-38 "A"] for a wide variety of FMGS' version and found nothing as well.
The closest resemblance is RWY/LS MISMATCH which is provided with explanation: During preflight or takeoff, the LS frequency entered on the RAD NAV page does not match the LS associated with the takeoff runway. So not close at all.
