Problem with a laptop is that most will only give you 60% of sRGB at best so in my book, not suitable for editing. I've got an HP Elitebook with a great spec, but I will never use it for anything to do with imaging as the screen is USELESS! When I got it (not intending it for editing), the blue cast was massive and I've been unable to correct it. My Azus is a bit better than the HP but has a lower spec and can only manage 58% of sRGB so that is not used for editing either.
Unless you get a laptop designed for imaging that, for instance a design studio would use, like The HP Zbook Studio G5 or an equivalent, making sure it has the best screen (they can ship with displays that are not to the best imaging specs) that gives as close to 100% of Adobe RGB like this one - HP DreamColor Display 39.62 cm (15.6 in) diagonal UHD IPS eDP with Panel Self Refresh (PSR), anti-glare, RG phosphors and LED backlit, 600 nits 100% Adobe RGB with 10-bit color (3840 x 2160) screen - you won't be doing yourself any favours. When I last looked at the machines that were suitable there were about half a dozen that fitted the requirement but I was not considering dumping my desktop that has an Eizo monitor which is calibrated regularly, and is the only machine I edit with.
I don't travel much though so in your shoes I might consider a laptop that is capable of producing accurate colours. Just remember that most wpn't.
