The Blub Paradox

If Lisp is more expressive than C, why Lisp can be compiled into C and C cannot be compiled into Lisp?

LISP isn't as portable as C(the portable assembler), in fact LISP in lisp machines died because it was unportable(openGenera is an emulator).
You can't claim that C,C that runs practically everywhere from a toaster to a space satellite is somehow restricted to specific hardware. C doesn't even require 8bit bytes(CHAR_BIT=8) and its types (stdint.h is a modern standard) are flexible to accept any machine word size.
Instead of claiming mythical dependency on von Neumann show a single example of hardware where Lisp does run but C does not.
C compilers exist for all architecture where it fits in RAM/ROM and its the industry tool of choice to create really specific software(microcontrollers,industrial devices,etc).
