I do not think so, and that is probably for a good reason.

A subtree biding can change over time, but .git/config is about
recording information that do not change depending on what tree you
are looking at, so there is an impedance mismatch---storing that
information in .git/config is probably a wrong way to go about it.

It might help to keep track of "In this tree, the tip of that other
history is bound as a subtree at this path", which means that
information more naturally belongs to each tree, I would think.
