Why do you want to use /10 prefix for link-local address ? RFC2373 defines link-local address format as below.
| 10 | | bits | 54 bits | 64 bits | +----------+-------------------------+----------------------------+ |1111111010| 0 | interface ID | +----------+-------------------------+----------------------------+

If you wan to use /10 prefix for link-local address, you can add the link-local address with /10 prefix to interfaces and routing table manually at your own risk, but it should not be a default behavior.
