I’m using a Canon 70-200mm f/2.8L IS II on a Canon 60D with battery grip and want to carry it on a sling-style strap. This lens has a tripod collar, but not dedicated strap lugs on the collar. Is it reasonable to attach one end of the sling to the camera body and the other to the tripod collar, or is that unsafe for the lens mount? My main concern is whether this setup puts too much stress on the EF mount, versus distributing the weight between the body and lens.

It should be, BUT: The question is, how secure is the screw. I think with those "black rapid" straps, people had the screw loosen.
While in terms of forces it should be no problem at all, I personally would not be so sure about the screws staying "stuck" reliably.

Generated from our catalog & community — verify before relying on it.
Using the camera body for one attachment point and the tripod collar for the other should generally be fine from a load/stress standpoint. A 70-200mm f/2.8 is heavy enough that supporting the lens at the collar is sensible, and splitting support between body and collar should reduce strain on the camera mount rather than increase it.
The bigger concern is not the lens mount, but the security of the screw-in strap connection. With sling straps that attach via a tripod socket screw, the screw can work loose if it isn’t checked regularly. So the setup is likely safe mechanically, provided the attachment hardware is secure and monitored.
In short: the carrying concept is reasonable, but make sure the screw connection is tight and reliable.
