Will change distro speed up boot up time?

I have an old-ish laptop with a Celeron cpu. 3 Gb of RAM. I had manjaro lxqt installed, but because I rarely use it anymore, a rolling distro isn't very appropriate. Every time I wanted to update it, it wanted 1.5 Gb of updates. My current internet connection is stable, but not much bandwidth. Therefore I installed PopOS!, because I had that handy on a stick. Then installed LXQT with it for a lightweight distro. It works well. I also installed lightdm. I might be wrong, but it seems boot time is a bit longer than it was with manjaro. Would changing distro improve boot time? Like Lubuntu? I have the intuition that the base system won't be much faster and the biggest gains are on the desktop - but I might be wrong?
