Only with a separate PSU and a DC-DC SSR or an external MOSfet to switch it on/off

Could the I mod the Ramps 1.4 to 24v and will the arduino board handle that voltage?

I used a 24V 450W bed on a printer and would never do that again. Go with line power switched by an SSR. The SSR won't need a heat sink and you won't have to worry about burning up your PCB or MOSFETs with the high current that a 24V bed will need. Add an electrical fuse and a TCO for safety.
