That is not correct, Good Guy. Linux, and pretty much any operating system,
uses binary programs. Which means programs that consist of machine
executable op codes. And Apache HTTP server on Linux is no different: it is
a binary program. I would love to know where you got the idea that Linux
does not use binaries.

It's trivial to create a Apache HTTP server that can be run from a USB
stick if all of the systems have compatible architectures (e.g., x86,
x86_64, or ppc) and support libraries (e.g., the libc library). It's more
difficult but still possible to create a portable server even if those
assumptions are not true. You simply need to build everything from source
and specify an installation root directory that will be valid for all the
systems on which you want to run the server (i.e., a directory where you
can mount the USB filesystem or symlink to it). You can't simply copy the
httpd binary and related files that are created for a given distribution
because the various parts are spread all over (e.g., /usr/bin and
/usr/lib). Which is to say the only common directory for all the files you
need is root ("/").

P.S., There are very fringe, unusual, computers that directly execute byte
code for languages like Forth and Java rather than machine language as
typically understood by most CPUs. But even those systems are effectively
executing binaries.
