I agree with Alaska Man that things may depend on settings and, as a general rule, you'd better know what you are doing.

That said, I regularly delete this folder (on Windows) without ill effects. (I also set a fairly low cache limit). Once I process my RAWs, I rarely return to them, so there is little point keeping the cached copies.

If you are not sure, just rename the folder and see if everything still works in ACR, esp. when editing RAWs you recently processed already. (I prefer this explicit way instead of using Trash). Then, after a while, you can delete this folder permanently.

IMO, if the software calls something 'cache', it must be purely performance-related and should be safe to delete at any time when the software isn't running. Alas, this is not always true in practice, but if so, the software is poorly designed. Fortunately, this doesn't seem to be the case with ACR.
