Almost certainly.  Examine the format of symbol table entries, and see what
you can do.  There will be include files describing it - a.out.h perhaps,
and a man page for a.out.  Then write a program which reads in the .o
file, and writes it out with a modified symbol table.

A simple hack which may be enough is just to edit the .o file (using an
editor like gnu emacs which doesn't have line length restrictions).
Find the symbol name and change it to something obscure, being careful
not to change its length.
