It's true - usually it works fine; but sometimes you still must be aware of
the difference. For example, if I use network installation, I cannot instal
SP3 system if I use boot kernel from Sp2 system; if you keep old kernel, you
must kept old modules and so on/

Generally it is minor issue - YOU do not remove kernel which is not active,
so all you need to do is to add (manually) safe kernel into the system and
into grub menu, and then you can run YOU etc without risk to lost the whole
system.

This is solved with the kernel RPMs provided by SuSE since UL 1/ SLES 8
SP 2 IIRC. The following output is from a current SLES 9 system:
