It might seem a little roundabout, but you can use the SqlFunctions class' DateDiff method for doing this. Just pass in both values and use "Day" for finding the difference between them in days (which should be 0 if they are on the same day).

Like the following:

from a in _db.AgentProductTraining
                where a.CourseCode == course.CourseCode &&
                SqlFunctions.DateDiff("DAY", a.DateTaken, course.DateTaken) == 0 &&
                a.SymNumber == symNumber
                select a;
