Well, adding one system which moves with the minimum supported kernel
version probably wouldn't be too onerous, so I will add a ticket noting
this as a community request. On the other hand, one of the reasons we're
moving to running more and more of our testing from containers is so that
we don't have to do as much VM "babysitting" and our testing environment is
more cleanly defined. Obviously that doesn't apply in this case, so we'd
set up a custom VM for this testing job specifically. But, as an LTS kernel
version reaches EOL approximately 1x per year, it shouldn't be too bad.

Maybe the best thing we can do without a significant overhaul of our
process is to more explicitly display the kernel version for a system when
reporting results. If others chime in and there is big interest here, we
can go further.
