Likely. I'd trust a good mechanical gauge for setting it then use the TPMS as a reference. I.e. Set it to a known correct pressure then note AND watch the TPMS for any change. Mine is closer showing maybe 1 or 2 pounds more on the TPMS than the gauge. IMHO 1 or 2 pounds either way won't matter. It changes that much from a cool day to a hot day anyway. Good luck.
