No.  GPG simply does not allow importing of secret subkeys. (aka merging
of secret keys)  I've asked about this before, and a quick search
reveals several other people asking about it.  See
https://bugs.g10code.com/gnupg/issue318

This is also a problem when importing secret key stubs for a smartcard.
