I would get up as much of that glue as you can. If you are using a thin vinyl sheet flooring / thin stick-on flooring, then you need the floor to be completely smooth (no bumps or divots). Even a little bit of glue the size of a piece of rice will be noticeable when the vinyl is placed over it. Same with any divots / dents. When you pull the carpet up, check the subfloor carefully. Is it just plywood underneath?
If you're using thicker planks with built in pads then it doesn't matter near as much.
I just placed a whole bunch of the 12' wide thin sheet vinyl in several rooms. It's a great, very durable project. You can find it very cheap too. Of course it doesn't look / feel like luxury, but that's why it's so cheap.
Also be aware that the vinyl is probably a good bit thinner than your current carpet / pad. So switching our carpet for vinyl...you may have a small gap all around the perimeter of your kitchen where the flooring meets the wall / cabinet / etc (depending on how the carpet was installed). You can likely cover this gap with quarter round, but it's worth thinking thru before you make any definite decisions.
