I'm not too familiar with big tech companies blocking booting from USB, though it is a pretty common practice in the finance sector, iirc. There's an apocryphal story of a security researcher who was tasked by a bank to break in if he could. He littered CD's around the parking lot (or was it USB drives? I forget) back when auto-run was a thing. Employees saw the disks on the ground, picked them up wondering what they were, and inserted them in their work computers to find out. Tada! Access granted. As such, Big Corporate companies (finance, insurance, retail, etc) tend to lock down their computers pretty hard... tech companies less so, I think. Personally, I'd just take two laptops.
