Yes. Just highlight text in red and green, with strike through or
underlining.

If you write the paper in LaTeX you can use macros like:

\definecolor{addclr}{rgb}{0,.6,.6}
\definecolor{remclr}{rgb}{1,0,0}

\renewcommand{\added}[1]{\textcolor{addclr}{\uline{#1}}}
\newcommand{\removed}[1]{\textcolor{remclr}{\sout{#1}}}
\renewcommand{\changed}[2]{\removed{#1}\added{#2}}



I mean, you can't diff(1) a PDF, can you? :)
