Just today I upgraded from 39 to 40 but there was an issue:
dnf told me I needed some 800k more space in my /boot partition to proceed.
I had two kernels in /boot so I dnf removed those associated with the older
of the two kernels. I then successfully upgraded.
I fear the next time I do a dnf update which includes a new kernel I will
be told, again, that there is not enough space in my /boot partition.

So, how can I increase the size of the /boot partition? Many partitions,
like /tmp, are bigger than they need to be.

Here is what how the /sda disk is organized.

This looks like you've been upgrading for a very long time. This type of layout and partition sizes is ancient. /tmp isn't even a partition now.

The easiest option would be to use a live boot, shrink the /ssd partition by 1GB, shift it forward, then give that space to /boot. I assume that gparted can handle LUKS. And of course, make sure you have a backup for whatever is in that partition if it's important.

An alternative would be to reformat the /tmp partition for /boot, move the contents, adjust fstab, and update grub. But that's a lot more space than needed.

Thanks for any help give.

I realize one way is to backup /home and then reinstall Fedora but
1) that seems like a lot of work,

Yes, but maybe it's time. :-)

2) it would mean that the machine in question would then have to
use Wayland rather than Xorg and

Why would that be? You must have been listening to some misinformation. If your current install can use Xorg, then re-installing won't be any different.

3) with Wayland I could not use xfce4.

If you install with xfce, then that's what you'll be using...
