Some FS2004 scenery works in FSX. It's kind of hit & miss.
Some trees & buildings may not appear because they might refer to files in the FS2004 object libraries that are not in the FSX libraries.

I also find that some does but in my opinion not very well, it is better to only add FSX scenery especially if using the excellent Horizon photo scenery.
