No. The internal FW isn't necessarily backward compatible [there are some Compatibility in fastpath in order to support VFs, but not in general]. Doing what you ask would means filling the driver with a lot of legacy code for older FWs, adding per-FW version HSI files, etc. So in short - if you've installed a fresh kernel on top of an existing distro that lacked the latest firmware in its filesystem, getting that missing .bin file from linux-firmware is the way to go.
