It is incorrect to say that an executable file is machine code just because 
some segments contain opcodes. Just like object files, executable files 
contain different segments, not all of them are executable.

You can, in the correct context, say that an executable file contains 
machine code
as the executable section normally does contain machine specific opcodes.
It is incorrect however, to assume that these opcodes can be executed 
unmodified,
except in very rare cases that are nowadays no longer used, like the .COM 
files in DOS.
Further, the exe files contain other sections, like data sections, which are 
not opcodes and
cannot be executed by a processor. Even the old fashioned .COM files 
contained data that
were not opcodes.
So, there is a difference between object files and executable files, but the 
difference is not
that only one format consists only of opcodes that can be used unmodified by 
the processor.
