No.  A language is Turing-complete if it can be used to implement a
universal Turing machine.  What you quote is merely a consequence of
Turing-completeness, not its definition.

The operating system, the C++ compiler and the linker are all written
in C, and using C, you can write an emulator for the computer, on
which the OS, C++ compiler and linker will behave exactly as you
expect.
