No, not without special permission from the SLA Program. On rare occasions exceptions are made to allow students to attend SLA who are not enrolled in the SLA course section. However, the best way to participate in SLA is to see if it's possible to obtain special permission from the course's departmental office to officially enroll in the SLA course section. You may also contact the SLA program coordinator for assistance. The SLA program does not wish to deny any student who really needs and wants SLA.
