You're right, it's technically true of any program, but it wouldn't necessarily be practical. Implementing CPython on a Gameboy Advance, for example, would be tedious and likely not entirely possible.
The purpose of Bedrock was to make a system that is easy to implement on as many computer systems as possible. I've got plans to make a working system from a 64KB RAM chip and a $2 PIC12F1572 8-bit microcontroller (2K memory, 6mW power, 8 pins), just to see how far down I can take it.
