Yes you can do it like that:

public List SearchByMultipleKeyword(string keywords)
{
    string[] keywordsSeparated = keywords.Split(',');
    var results  = (from a in Entities.TblActivities
                    where keywordsSeparated.Any(keyword => a.Keywords.Contains(keyword))
                    select a).ToList();
    return results;
}
