It's allowed in that it no longer invalidates your warranty, but I don't think there is any guarantee it will work. Overclocking also puts more load on the PSU, so there is potentially less power available for the SD Card to work with. Perhaps a write failed due to power issues in Turbo mode? What is your PSU rating? 0.7A is the recommended amount the PSU should be able to supply. As an aside, I have also been thinking of using NILFS root, but struggled to get the default kernel up and running with an initrd (to load the nilfs2 module). Did you use a built in nilfs2 driver? A raspbian image with NILFS root would be awesome, given the performance benefits of NILFS on lowe end FLASH media.
