Two part question, two part answer.
No.
If it's stored in the database as a truncated hash you could easily write a cracker that could generate a collision within minutes.
If it's not stored in the database as a truncated hash and you just somehow "lost" the other 22 characters, then there's nothing you can do to get the original hash back. Even if you did generate a list of every possible double MD5 hash that started with those 10 characters, there will be thousands of collisions.

No.
