No. The 16 file would have to be saved as a 15 file, then that 15 file saved as a 14 file. Since 14 cannot recognize the new features in 16, it might make more sense to do all the work in 14. If all the work is only 2D, then you could save the 16 work in another file format (dwg, etc) that could be opened in 14.
