Seems fixed. I just tried this:

sbuild -d bookworm supermin

on a stable system still running 6.1.0-29
(upgraded to -31, but not rebooted yet).

The build process installed linux-image-6.1.0-29-amd64,
the package was built, and sbuild was able to remove
the kernel even if it had the same version as the
running kernel:

[...]
Removing linux-image-amd64 (6.1.123-1) ...
Removing linux-image-6.1.0-29-amd64 (6.1.123-1) ...
W: Last kernel image has been removed, so removing the default symlinks
/etc/kernel/postrm.d/initramfs-tools:
update-initramfs: Deleting /boot/initrd.img-6.1.0-29-amd64
Removing initramfs-tools (0.142+deb12u1) ...
Removing initramfs-tools-core (0.142+deb12u1) ...


Apparently linux-check-removal is smarter now:

---------
If the currently running kernel matches VERSION, linux-check-removal
will normally prompt the user to confirm this potentially dangerous
action and will fail if the user chooses to abort.  However, if the
current environment is in a chroot or container, or if debconf
prompts are disabled, it will always succeed without prompting.
---------

I traced that to commit [4a695de] in linux-base, dated 2016-06-06
(which is just two days later than the last message from Ben
in this thread).

     Add linux-check-removal command for use by package prerm scripts
     
     Use the existing logic (roughly) and exactly the same debconf template
     and translations that are currently included in src:linux.

Therefore, I think this was fixed in linux-base 4.3.
Closing myself.

Thanks a lot!

This was actually fixed even longer ago, before the logic was moved to
linux-base.  The src:linux changelog(.old) has a Closes: reference to
this bug but it looks like this got lost on its way to the BTS.
