No. IIS Express is not IIS 7 (derived from IIS 7 code base does not mean there is no difference.

Besides, the most important thing is your web application may have indirect dependencies on the OS, which can be quite different from Windows XP to Windows 7.

So if your goal is to test compatibilties, doing that on Windows 7 or Windows Server 2008 R2 is necessary.

Yes. You can use IIS Express to test your app on XP. (IIS Express requires XP sp3)
