Maybe this will help. It did for me.
I have an IdeaPad 720s-15ikb and have been strugling to find a fix for the trackpad laginess for months and recently found a quick fix.
It seemes that lenovo function software has some hidden features. Hit Fn + Q and set the profile to performance. I have been using the laptop like this for some time without any lag

Well, that did not work for me. The touchpad is still laggy. But its a pretty interesting direction for solving & understanding the origin of the problem.

For me the TouchPad is still sluggish but the random jumps of the cursor when I click on the TouchPad seem to have disappeared since the major update of Windows 10 entreprise (Update of last fall 2018).
I updated it 3 weeks ago or so...
Lenovo sucks. We never got any member of their team to respond to us here in a year... Shame.
