This might be pretty much manufacturers specific, though one can argue that they tend to use the same board, thus the same rule
A good part list on the board circuitry is what you need.
Voltage regulation on notebook to me is more a stabilizer than a regulator
that is capable to take a wide
range of input and managing it. A little difference maybe. One can also argue that based on the battery specs, why not just use a smaller adapter (ex of 11v battery = 16v adapter)?
Still I don't quite follow the statement of " It could be possible that laptops these days can actually take a pretty wide voltage range if engineers used the correct voltage regulation circuitry
" - to me they already use the correct voltage regulation circuitry meant for the specific environment, notebooks in this case, taking in consideration all other electronic components on the board. Those requirement of certain power input are being taken in consideration when such or such power adapter is needed.
