I have the "Student Guide to Credit by Examination at Excelsior College", which you can download from their website. It has lists all of the CLEP and DSST exams offered, and the only two I could identify that might qualify for business communications were the DSST Principles of Public Speaking, and Technical Writing. You would want to get prior approval from your advisor before taking these, to be sure they'd meet the requirement.
