Well, I suppose wavelength would be subject to the same errors that plague the speed of light as
V = F * (lambda) Since the frequency is from a standard material, the wavelength and velocity are inseparably related. Any modification in one will cause a change in the other. Since the second can be determined to such precision I suppose it would be -- but how do you measure out 1 / 299 792 458 th of it to a similar precision? Please note that accuracy is a comparison to a standard value, and precision is comparison to other results from the same machine. Precision machines can be calibrated to pinpoint accuracy, which brings up a confusion between the terms when you talk about the standards to which the standards are to be measured.
