when I was young and stupid, when I bought my house, we ripped out the old tile, and the 1970's/80's lino without wearing masks.
We found it was not possible to peel/scrape off the lino, was too brittle. so we had to pry the subfloor, and of course it was particle board so it would break into small pieces as you pry it up. The previous owners tiled right over the lino, which failed miserably.
we used pry bars and a shovel and a rigid shopvac with the hepa filter just like kevman.
house was built in 1971
