I haven't tried 4.0 ---> 4.3, but I have done 4.1 and 4.2 upgrades to 
4.3.  I haven't experienced any problems using this method:

<root passwd>
yum update
(hit YES when prompted)
(go out for a cup of coffee while it downloads and updates)
/sbin/shutdown -r now
(system wakes up as CentOS 4.3 box)

It's THAT easy.  These were all rather vanilla systems without any 
special drivers or custom kernels that were just doing standard 
DNS/mail/web services and it just plain worked.  The CentOS team did a 
great job!
