I think the answer to that is "kinda". Let me explain.

It will likely be difficult to keep the packages perfectly in sync,
but a brute force approach would be to use the yum downloadonly
plugin. The would download the update RPM's without actually
installing them, then you could copy those to an external drive or
thumb drive, then run yum update again to let the transaction
complete.

The problem would be if you forgot to add the --download-only (or
whatever it's called) option EVERY time your did a yum update on the
development box.

There might be (and probably is) a more elegant solution but that's
all I can think of.
