Back in the day when I replaced the battery in my MBP, I recall the battery was a significant part of the total weight.
To build an all day running ultra-light would probably require a magnesium case, but magnesium and lithium are both flammable metals. Probably not ideal on an aeroplane. Using more plastic doesn't meet the premium requirement.

I'd guess, unlikely?
