Yes it is possible to use a single power supply to power two boards.

The only issue you will have is with the shared power button. Both will power on and power off the unit at the same time. It will not cause any damage of any sort as long as the PSU capacity can handle both systems.
My recommendation is to only have one mobo have the power button connected and it will power on both boards.
Alternatively you can:
- disconnect the green PS_ON wire from both boards and use a single rocker switch to force the unit on, and use the reset & power buttons on the case for the reset
- disconnect the green PS_ON wire from both boards and simply short it to ground (forcing always-on) and use the ATX power supply rocker switch in the rear of the unit (if it exists) to power the unit on/off. If the unit is autosensing / active PFC the seperate rocker switch above is the better alternative solution
cheers

No. Since the boards both return voltages to pins for reading case button presses etc, there will be conflicts which can destroy a board. And this would still not allow both boards to work together, it requires very specialised software to parallel run the systems, and almost a computer degree to configure and maintain it.

well its depend on material feasibility in market. if u want to use same power with 2 differnet boards then it will we danger issue with both of boards nd 500W supply cant hold it
