No.  For students with IEPs and those with 504 plans, Section 504 prohibits discrimination against students with disabilities.  Preventing students with disabilities from participating in extra-curricular and non-academic activities (such as counseling services, physical and recreational activities, transportation, special interest groups or school-sponsored clubs, during or after school) is a form of discrimination.  [34 C.F.R. Sec. 104.37.]  In addition, if a student’s IEP specifies any of these types of activities, the related services necessary to enable that student to participate, such as nursing services, must be provided in order to comply with the IEP.  [34 C.F.R. Sec. 300.107.]
