Only if they don't show on your report (only because the credit report is what Chase checks). From a banks, such as Discover and Cap One, business cards do show up on credit reports, and so do count toward 5/24.
Thus it's best to actually look at your credit report and count the way Chase counts, rather than by trying "guess" what might be on your credit report.
