Yes. If you want to decrypt mail for your private address at work or v.v., you need both keys. It's possible to transport your secret key to another machine. Use gpg --export-secret-keys > filename. Then transport the file you created by a safe means to your other machine. Mailing it encrypted to your work address would work, or sftp if you have it. I wouldn't use ftp etc, since that would send your private keys over the net for anyone to catch.
