Depends on whether you want to pull the chip out of it or not......
I don't own a Leonardo, but I know they don't do an old school 28 pin chip in an old school 28 pin socket version. They used to do a SMD (surface mount) version of the arduino Uno, I don't know if its still available.
If you wanted to take a surface mount chip off a bourd it involves special kit and melting solder.......
