You're actually touching on an important distinction here, but in the wrong direction.

The amount of body fat you need for essential functions does not scale linearly with your lean mass. The more lean mass you add, the lower your safe minimum body fat percentage will be, because your essential body fat is partly made up of things that don't "store fat."

Someone with essentially zero additionally developed muscle mass (or in severe cases of long term atrophy) would certainly need a higher % body fat for essential functions, compared to someone who lifts weights and has packed on lean mass.

And that makes sense. Different tissues require different amounts of fat to function well. Nervous tissue needs plenty, but muscles not as much. Thus by adding muscle mass, you decrease the minimum body fat % for healthy function. (and in fact the muscular person could have a greater total fat mass than the underweight person).

I havent read that, or found anything saying that online. I heard the percentage stays the same. But based on you body size, the amount can change (but thats because the percentage stays the same). Thats just based on research Ive pick up on this along the years But I dont see how that would change anything. You mention how muscles wont need as much body fat to function, but that should matter. More muscles dont mean less body parts that need fat to function. The rest of the body should still need the same amount of fat to function The muscles were already there, even if they werent worked on or smaller. And with the muscles, you still should have the rest of the body that needs the essential body fat
