Sure thing.
First on the piano track right click and in the drop down menu go to Select RealTracks and in the next menu go to select RealTracks. This should bring up the RealTracks picker
Up in the top left of the RealTracks picker is listed all of the RealTracks in the song next to Bass, Piano, Drums, Guitar. Next to Strings it says 2642 Piano Tango Ev 100. If the Radial button next to piano is not already selected select it now.
Just below this and before the list of RealTracks are two buttons, one says None, the other says Clear All. Press the None button to remove the piano track and then close the RealTracks picker.
Now if you assign the style SENSUAL from the style picker the horn section will appear.
