You won't find ANY long term support distro which supports the 'latest' kernel, or even close to the latest. If you have bleeding edge hardware, you will have to put up with bleeding edge software headaches and lack of support. Even developers require SOME time to write software to support their bleeding edge hardware, and longer to debug it so the hardware drivers don't cause regressions (bugs caused in previously working software/hardware by the update).
Especially on LTS versions like Debian Stable, Red Hat Enterprise Linux (and derivatives CEntOS, Scientific Linux, etc.), SuSE Linux Enterprise Server, and Ubuntu Linux LTS versions from which Mint LTS versions are derived, kernel variations are a headache that they can't afford to support to cause breakages on thousands of machines.
If you want the 'latest' technology, you will have to learn to live with software and drivers which have not been completely debugged, such as Debian Unstable (a.k.a. Sid), Fedora, Arch and its derivatives or pre-alpha versions of one of the more 'stable' distros. Often on these distros, it can take 3-6 months after the release to public to swat enough bugs to make the distro release mostly usable for 90% of the users. That is why Debian has actually 4 branches:
old-stable=almost bedrock solid stable, has had 99.99% of bugs swatted after 4-6 years of debugging packages approved for use. Packages/kernel are getting long of tooth, but are still useable on most modern machines, especially server hardware. Was the stable release prior to the new stable release.
stable=very stable, good for at least 2 additional years of support after release date; excellent for servers or stable desktop use. All reported bugs have been squashed before release from testing.
testing=all packages have gone through extensive testing and debugging while in the unstable (Sid) repositories, but may have some outstanding reported bugs. Repositories are snapshots of the better packages of the unstable/experimental branch called Sid. The repositories are named after a Toy Story character for tracking purposes at this point in the release cycle. When all reported bugs are fixed, the repositories become part of the 'stable' or released version. The kernel version and package versions of all software are fixed during the package freeze portion of the cycle prior to the final bug fix cycle so that there are fewer interactions to cause regressions in previously stable software.
unstable= Sometimes called experimental, always called Sid. Bleeding edge packages direct from the upstream developers are released to the Debian developers and any users who want the very latest packages and don't mind reverting to older packages if needed, reporting bugs to developers and waiting for bug fixes in the next package release. Ubuntu and Mint, except for Canonical or Mint exclusive packages, are snapshots of Sid.
