I'm using Archlinux on Thinkpad T440s with 8Gb ram and i5-4300U processor. It usually gives me on average 5 hrs of battery and it's lightweight to carry around.

The primary factors I chose thinkpad was due to 1. Battery backup 2. Awesome Keyboard 3.I wanted 14inch screen size.

Answering your question, Even a chrome book would suffice for web development, all you need is a browser and editor. It's really upto you to see which laptop suits your need.I suggest you do this.. 1. Write all the specs you think you need like screen size, battery life, if you need a GPU or not, weight of the laptop... 2. Check the top brands (Lenovo t,x series, Dell xps, HP, toshiba...) using those specs as filters and make a list of laptops you want to finally choose from 3. Go to a store and try those laptops out firsthand, see how comfortable you're with the keyboard etc..

A browser and an editor is far from enough for web development. At the very minimum you will need node.js at the very least for task managment and build process, all the browsers and VMs to load IE and Edge testing plus maybe Photoshop, or at least some kind of industry acceptable image/design software.

Yeah definitely, but it's not really necessary to run them on your laptop. You could simply vnc into a remote machine to use tools like photoshop etc. As for nodejs or any other building tools they don't affect your choice of laptop.

If you need performance then you may have to sacrifice battery and weight. if you need something you can carry around you have to give up performance as your primary choice.

I don't know about you, but I need much more than "a browser and an editor" on the laptop. I run a lot of apps outside the browser, I create VMs, etc. That RAM and a decent processor are crucial to me.
