Running Ubuntu under wsl. Issuing wsl.exe --status in Windows (11) returns

Default Distribution: Ubuntu-22.04Default Version: 2Windows Subsystem for Linux was last updated on 27-Mar-22WSL automatic updates are on.Kernel version: 5.10.102.1

and uname -r from within Ubuntu says 5.10.102.1-microsoft-standard-WSL2. But the /boot directory contains

drwxr-xr-x  3 root root      4096 May  4 20:29 ./drwxr-xr-x 19 root root      4096 May  4 21:01 ../-rw-r--r--  1 root root    260489 Apr 14 08:46 config-5.15.0-27-generic-rw-r--r--  1 root root    261613 Apr 27 14:06 config-5.15.0-28-generic-rw-r--r--  1 root root    261233 May  3 14:20 config-5.15.0-29-genericdrwxr-xr-x  2 root root      4096 Apr 19 14:05 grub/lrwxrwxrwx  1 root root        28 May  4 20:29 initrd.img -> initrd.img-5.15.0-29-generic-rw-r--r--  1 root root 118149011 May  4 20:29 initrd.img-5.15.0-27-generic-rw-r--r--  1 root root 118191763 May  4 20:28 initrd.img-5.15.0-28-generic-rw-r--r--  1 root root 118173389 May  4 20:29 initrd.img-5.15.0-29-genericlrwxrwxrwx  1 root root        28 May  4 20:29 initrd.img.old -> initrd.img-5.15.0-28-generic-rw-r--r--  1 root root    182800 Feb  7 00:35 memtest86+.bin-rw-r--r--  1 root root    184476 Feb  7 00:35 memtest86+.elf-rw-r--r--  1 root root    184980 Feb  7 00:35 memtest86+_multiboot.bin-rw-------  1 root root   6241791 Apr 14 08:46 System.map-5.15.0-27-generic-rw-------  1 root root   6248105 Apr 27 14:06 System.map-5.15.0-28-generic-rw-------  1 root root   6248105 May  3 14:20 System.map-5.15.0-29-genericlrwxrwxrwx  1 root root        25 May  4 20:29 vmlinuz -> vmlinuz-5.15.0-29-generic-rw-------  1 root root  11064224 Apr 14 08:47 vmlinuz-5.15.0-27-generic-rw-------  1 root root  11081440 Apr 27 16:32 vmlinuz-5.15.0-28-generic-rw-------  1 root root  11081856 May  3 14:32 vmlinuz-5.15.0-29-genericlrwxrwxrwx  1 root root        25 May  4 20:29 vmlinuz.old -> vmlinuz-5.15.0-28-generic

which seemingly indicates that the current kernel version is 5.15.0-29.

How to understand this?

And by the way, can I delete the -27 and -28 entries?
