This game
Nanny Mania require windows 98 but when I try to install it, the pop up require windows 2000 or newer. If I install linux on my windows 98se, would I be able to play play a windows 2000 game on windows 98se?
Linux is not a compatibility layer, not even a Windows-based software. You don't install in ON windows, it is an Operational System by itself. It runs several Windows-based applications though, if WINE is installed.

How do I use the Orca to be able to play a windows 2000 game on windows 98se?
Orca is only able to edit MSI files (used by some installers), and it can be used to remove (or alter) the OS check done during the install process. If the software itself is really not compatible with Windows98 (uses unsupported functions, for example), there is nothing Orca can do. In that case you could give KernelEx 0.32a a shot. It patches a few system files in order to add some of these functions.

I don't think there is very much difference between windows 98se and windows 2000 that would prevent windows 2000 games from playing on windows 98se if I install it.
Actually, Win2K supports functions Win98 does not.
