EDIT: Never mind, I think I found my answer:
"Accelerometer data from the navX-MXP’s onboard MPU-9250 are double-integrated by the navX-MXP firmware to estimate displacement, and are accurate to approximately 1 meter of error during a 15 second period."

So it's a definite no.
There's much discussion on chief Delphi on how to address this. It's pretty well known that there is currently no single sensor that can track position to the required accuracy for FRC. Teams are having success by a solution that fuses multiple sensors:

- wheel encoders + navX-MXP
- vision processing w/camera w/navX-MXP
- a combination of all of the above
- using a "follower wheel" that has a wheel speed encoder (for distance traveled) and an angle encoder (for current direction of travel).
