It's not the case that it won't work it's the case that it's unsupported. If you get a problem and raise a PMR then you may be told to down grade Domino. I have heard of some odd occurrences when the versions haven't matched but not many because most people install the supported versions of the software. Unless you have a real valid reason as to why Domino must be version 9 I would reinstall or be prepared to reinstall when/if you come across a problem.
If you installed version 9 because of the rest of your estate is running Domino 9 then put Sametime in it's own Domino domain. It doesn't need the address book or all the other databases, in fact it's better if it doesn't. This would allow you to upgrade everything else and not effect Sametime and vice versa.
