JCM2000 DSL50 and DSL100 main board differences

[Cascadem]

I have a JCM2000 DSL50, I happen to own a brand new (latest revision) main board for a JCM2000 DSL100. Can I simply remove some components from the 100 board and just run the 100 board in my 50?

I still need to compare schematics, but I recall seeing the main board of my 50 before and I thought I remember seeing that it has spots for parts that the 100 would use. Is it so, same board just populated for one or the other 50/100watt?
