The answer is no. If you wish to use a gold guest list redemption to open up reward space it has to be on a BA operated flight. Below is the line plus more details from the section in post #1 to which I referred. I don't think it's hiding.
This is by far the most sought after benefit, as it allows you to make two return bookings per year on BA flights with Avios booking into revenue available seats as follows:
Book up to 5 seats using avios even when there are no redemption seats available
Limited to 5 joker seats per cabin per flight (though the GGL can request additional seats on your behalf)
Seats needs to be available in revenue classes (A for first, D for CW, T for WT+)
All flights must be on BA metal (cannot be used on codeshares with AA, CX, etc.), though can be combined with itineraries with seats on other metal if normal availability is available on those flights
May be used for other people, even if the GGL member is not flying
