Difference in what?
Oh, I see... You put some critical information in the subject
and failed to include it in the body of your message. The
relevent information is "text files".
So, I assume your question is "are there any differences between
text mode and binary mode, other than '\n' interpretation? "
I rather think the OP meant to ask whether there were any other
differences apart from end-of-line interpretation, between different
text files on different systems.
To the OP:
As far as text files of different system's are concerned, they are
meant to be portable, and to a Standard C program, there should be
no difference between text files created by it and those created by
other implementations .
Under the hood, there may well be many more differences than just the
end-of-line one, but they're all supposed to be well hidden by the
operating system and the C library.

No. Text files often have a control Z as end of file marker. However on most
systems the text and binary formats are in fact identical.#

AFAIK, this is rare among most modern systems.

So you think most systems are not DOS/Windows/VMS/MacOS-9/whatever? I'm
sure at least one other OS I know has a different format for text files
to binary files, but I'll stick to the ones where I know there are
differences. Also, remember that Windows probably includes WinCE and its
successors which are used in some PDAs and mobile phones.

What exactly does "binary format" mean? On many (most?) systems,
there's no such thing as a "binary format" -- or rather, there's a
practically infinite number of such formats, at least potentially.
A text file is (usually) just a special case of a binary file, with
some structure imposed on it.
Now it would make sense to ask what translations are performed when
access a file in text mode as opposed to binary mode, but I'm not sure
whether that's what the OP asked.

And what are "most systems"?

A catch-all name, I presume, for all human-unreadable

Binary doesn't necessarily mean human-unreadable. Those amongst us who
have written programs in binary, as I have, will almost certainly agree
that, whilst reading binary isn't necessarily top of their Ten Fun
Things To Do Today list, it is nevertheless possible.
In any case, if you're right /and/ Malcolm is right, then text files are
unreadable too, on most systems. Is that your contention?
