Taking classes at peabody

If I get into Johns Hopkins, can I take courses at peabody? I would not be applying to peabody.

According to http://eng.jhu.edu/wse/asen_undergraduate_handbook/registration-policies, “Homewood undergraduates who are not enrolled in a music major, minor, or degree program may take only one nonperformance course per semester at the Conservatory or Preparatory. These students may also take one performance course concurrently with the approval of the student’s academic advising office.”
