Well in case anyone does a search, here's my results. I did end up buying
This Lenovo T440s. i7, 1080 screen 12GB RAM, 256SSD etc. I copied my EQ folder from my desktop and installed Win EQ2 and just launched it without changing anything.
The game opened fine. Performance was a bit poor so I did turn down most things like spell particles and sky and all that. I had to bump up the gamma because it was excessively dark.
EC is chunky to be expected but soloing on my mage in WK is just fine. Around 30 FPS and the laptop isn't really breaking a sweat, not hot, no crashing after about an hour.
Something with a dedicated GPU will obviously be better but for a super light and compact option that was pretty cheap I'd say it's fine.
