Well, that would be wrong thinking.
Far too many things and places in its hook-up that can go wrong and/or pick up noise.
Solid, independent, reference source is what you want.
And run unloaded, that example battery will continue to produce the 1v8 reference based on its chemistry for 20 years (according to the manufacturer).
Plus, you can use the battery in other devices when not jail breaking your Kindle.

"When I actually do the jailbreak [a] few years ..."
In that case, postpone your interface planning until then.
Things change rapidly in the field of electronics.
In fact, you would be better off to wait until your ready to do the work before asking questions.
Our answer a few years from now may not be the same as it would be today.
