I can\'t test it but I need to know if it real , because I started working on project for it with .NET 4 so I must to be sure I can install it there.
So can I install .N
Yes. Is possible because I use it. On Microsoft site you can find:
wic_x86_enu.exe (a prerequisite for my kind of image)
dotNetFx40_Full_x86_x64.exe (the library itself)
Based on the wiki entry for Windows XP Embedded:
Windows XP Embedded, commonly abbreviated "XPe", is a componentized version of the Professional edition of Windows XP.
So I'd say yes, because .NET Framework 4 is compatible with Windows XP Professional.
I can double some of the previous posts, that this works. I have successfully installed a .NET 4 Application on a Rohde&Schwarz ETL TV Analyzer. It even worked with the usual Visual Studio Setup project, including all prerequisites.
Kinda Cool!
.NET 4.0 Framework Template available
Microsoft has published a Windows XP Embedded template for the Microsoft .NET Framework 4.0 and .NET Framework 4.0 Client Profile.
The template can be used with the Image Configuration Editor. It will add all required packages automatically to ensure that the framework works properly with Windows XP Embedded.

Microsoft has a KBEntry about installing .NET Framework 3 on Windows XP Embedded, here: http://msdn.microsoft.com/en-us/library/bb417255(WinEmbedded.5).aspx
For .NET Framework 3, the answer is "yes" -- but, because Windows XP Embedded is componentized, you need to make sure the Windows installation that you're trying to use has all of the necessary components, and it's quite a long list. I would expect the answer for .NET Framework 4 is the same, although it may require additional components. This does mean that you can't assume that .NET Framework will run on any arbitrary Windows XP Embedded installation.
