No, you cannot do this in an AVR. The architecture is Harvard, not von Neumann. The program bus and data bus are totally separate systems. That means there is no possible way to execute code in RAM, not even any way to jump into RAM. But of course you can set flags in RAM and execute different bits of code in ROM based on the flags. The Select Case construction does this. So does any If statement.
