I guess it depends on the kind of "Linux" you want. Corporate IT will probably roll out RHEL or similar to the desktops, take away your root access, and install a virus scanner too.
I recall Arch, Ubuntu, Debian and Fedora being used. Relatively small shop though, like 40 devs.
Ironically we were contracting with ASML at the time and ended up having to work on Windows machines using Remote Desktop 99% of the time.
RHEL is very popular on servers but not on desktops. Which is in part due to Red Hat themselves, they don't really do much to promote it for this usecase. Personally (as an admin) I don't mind because it's such a closed ecosystem anyway. They're always rent seeking which Canonical does a lot less. Canonical is always trying to sell us landscape though, but we never went for it because it doesn't solve any of the issues we have with the existing tooling.
Personally I wouldn't touch redhat with a 10 foot pole after what they pulled with centos, however if my work did want to I'd make an effort on their behalf. They don't seem to though.
