List of Ubuntu Versions with Corresponding Linux Kernel Version
Is there a list of Ubuntu versions with default corresponding Linux kernel versions somewhere?

- 16.04, 18.04, and 20.04 are the only currently supported releases (as of Aug 18, 2020).
- This lists the kernel version that ships with Ubuntu, but new minor versions may be installed during the Ubuntu installation if updates have been released since.
You can get the list of the Ubuntu versions and their corresponding kernels from Wikipedia:

Take a look at this version table or this directory listing. I think that is what you are interested in.
Image manifest
You can see which packages are pre-installed as mentioned at: How to get a list of preinstalled packages?
E.g., on Ubuntu 18.04, the packages are at: http://releases.ubuntu.com/18.04/ubuntu-18.04.1-desktop-amd64.manifest
Then, since I know that my kernel is located at: /boot/vmlinuz-4.4.0-141-generic, to find the package name I did:
apt-file search /boot/vmlinuz-4.4.0-141-generic
which gave:
linux-image-4.4.0-141-generic: /boot/vmlinuz-4.4.0-141-generic
So I just search for linux-image- in the .manifest and it gives:
linux-image-4.15.0-29-generic 4.15.0-29.31
so I conclude that Ubuntu 18.04 comes with Linux kernel 4.15.
packages.ubuntu.com
If you search for the package name on Google: linux-image-4.15.0-29-generic, it also leads us to the packages.ubuntu.com page: https://packages.ubuntu.com/bionic/linux-image-4.15.0-29-generic
Then, on the breadcrumb navigation in that page, there is a link to the "kernels" section: https://packages.ubuntu.com/bionic/kernel/
And by searching for linux-image- in that page, we find several kernels that can be installed in the system.
The Ubuntu release cycle page keeps an up-to-date graph of the recent releases:
