Can the modules for SEM-DSC PowerSeries be used with the PowerSeries Neo/Pro?

No. The DSC PowerSeries PC1616, PC1832, and PC1864 panels use a different communicator module than the PowerSeries Neo and PowerSeries Pro panels. The correct communicator module must be used for the system to communicate to Alarm.com.
