You can’t change the names for Ubuntu kernels because so many programs refers back to the original names. Take for example my current kernel 4.14.34:
$ locate 4.14.34 | wc -l
70192
$ ll /boot/*4.14.34*
-rw-r--r-- 1 root root 1496011 Apr 12 05:53 /boot/abi-4.14.34-041434-generic
-rw-r--r-- 1 root root 213406 Apr 12 05:53 /boot/config-4.14.34-041434-generic
-rw-r--r-- 1 root root 58514444 Apr 28 13:36 /boot/initrd.img-4.14.34-041434-generic
-rw-r--r-- 1 root root 0 Apr 12 05:53 /boot/retpoline-4.14.34-041434-generic
-rw------- 1 root root 3952348 Apr 12 05:53 /boot/System.map-4.14.34-041434-generic
-rw------- 1 root root 8607504 Apr 30 03:52 /boot/vmlinuz-4.14.34-041434-generic
There are 70,192 files link to kernel version 4.14.34 but only five of them reside in /boot where you wish to do your renaming.
As mentioned in comments there is little danger of ArchLinux using the same kernel name as Ubuntu because they have their own unique numbering system: How do I map Linux Kernels to Ubuntu Kernels?
NOTE: At the time this was run I had two Ubuntu 16.04 partitions mounted so the 4.14.34 file count is 35,096 for a single 16.04 installation. Also note headers are included which I believe are optional but which I always install “just in case”.
Large listing
Below is the beginning of the locate listing. If vmlinuz were to be renamed the module files would likely not be locatable:
$ locate 4.14.34 | head -n1000
