You don't really want to saw it - it will make lots of dust.
Use a fubar or similar to smash a hole in it, and then tear it down with
your hands. Wear a hard hat and some decent work gloves and - ideally -
a face mask.
Bear in mind that the plasterboard will have been put up before the
walls were plastered, so it will extend over the top of the wall plaster
- so be careful not to pull too much plaster off the walls in the process.
What's the current finish - is it just normal skim? If it's artexed or
stippled, it just might contain asbestos - so you definitely need to
make sure that you don't breathe any of the dust.
