If discovered in the high speed regime (according to boeing thats above 80kts) it is not considered to be a reason for an aborted take off.
We had something like that around 2 years ago with a crew that aborted close to V1 due to speed disagree (in this case caused by an alpha vane failure) and the aircraft subsequently left the paved surface and came to a stop on the grass. Thank god nobody was hurt and nothing was bent.
