You sure can, you can create a difference grid using the Saga tools.  
You also can use profile tools for liner features to compare route 
elevations.  One would expect the Lidar to win if it was processed with 
kinematic GPS.

      QGIS has a range of tools for comparing two rasters. Once you have
      converted your LIDAR data to a raster file, you will be able to
      compare the LIDAR and SRTM values. <br>
