Hi Sandro,
it think you can have a better answer in the GeoTools mailing list.
https://lists.sourceforge.net/lists/listinfo/geotools-gt2-users

Anyway, I guess you can get the envelope of the grid and check the
coordinates on it.

  File file = new File("/home/xxx/grid.asc");
  AbstractGridFormat format = GridFormatFinder.findFormat(file);
  reader = format.getReader(file);

  GridCoverage2D coverage = reader.read(null);
  Envelope2D envelope = coverage.getEnvelope2D();  // the envelope

  DirectPosition2D point_to_check = new DirectPosition2D ( x , y ); //
your coordinates

  boolean is_inside = envelope.contains(point_to_check);  // check if
point is inside the envelope
