This is not a CoreXY thing, but Marlin (which you didn't specify). Disable PREVENT_LENGTHY_EXTRUDE in configuration.

I guess you found out by now, but

M302 S0 ; disable all extrusion checking

Just borrowing this thread, is there a way to re-enable PREVENT_LENGTHY_EXTRUDE after the above command? I tried M302 S170 and re-enabled PREVENT_COLD_EXTRUSION, but not PREVENT_LENGTHY_EXTRUDE
