C could - in principle - do it.  As you point out, both are Turing Complete.
But, "in principle" is quite different than "in actual fact".  At the time
that article was written almost 15 years ago, the TPF systems in use
were running applications written in hand optimized assembly language on the
largest mainframes money could buy.  Everything about that environment was
optimized for speed - from partially populating disk surfaces to running the
thinnest possible operating system executive.  (In those days, TPF itself didn't 
even have memory protection, or at least, it was just being added as an OS
feature.)

The point is that it would have been nearly impossible technically to
rewrite all that in C and expect the same level of minimal path length/
max throughput.  Give the sheer transaction load on those machines, this
would have been a showstopper.

But that was then and this is now.  These days, much of that capability 
HAS been written in higher level languages because of scale-out architectures
and messaging/queuing middleware.  Instead of one very fast centralized 
cluster of mainframes, we see thousands of servers spreading the workload
and achieving much the same results.  This has it's own challenges.  Managing
a few things is harder than managing thousands of things.
