Can operating system work without kernel? I read so in a pdf. If it is possible, how does it happen? I often have doubt about the difference between both of them.

What we call the
kernel is the operating system's low level functionality.
On most operating system designs, there is a core component to do that job, even if named differently.
While it is possible to boot to a single process which would take care of everything on its own, it would still be the highest ranked process, not just a regular soldier (kernel analogy).
