Your question has already been answered.

The chip has 512 kB of FLASH memory that has been tested and verified.

Because it uses the same die as a chip with larger flash, it has additional memory beyond this. This additional memory has not been tested and is not guaranteed to work correctly, or exist on future versions of the chip, although there is a strong possibility that both of these are true. It is up to you if you want to accept the risk of using this additional memory in your projects.
