Yes, but you should probably use a shared /boot, which means 3 things:

1) Make /boot larger. 350MB should do.

2) ONLY format /boot during the FIRST installation. Each install will
throw its kernel in there, so formatting it after would be bad.

3) Change the menu entry name during each install, and don't forget to
change the name of the entry added each time you install/update a
kernel.
