If they built the kernel directly from tree, just pointing out the correct https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/lin... should be enough...

Since a company building it themselves hasn't gotten it in the form of a binary from someone else that they're just passing along to you and their use is commercial, they don't satisfy either condition of GPLv2 3(c), but they'd need to satisfy both in order to be able to exercise that option.
