The documentation has been updated in version 2.15.0 to describe this. But as the commit message of commit 83558a412afa ("fetch doc: src side of refspec could be full SHA-1", 2017-10-18) says, this functionality was available earlier.

You'll need to set uploadpack.allowTipSHA1InWant, uploadpack.allowReachableSHA1InWant, or uploadpack.allowAnySHA1InWant on the server. (This might need to be better documented - I see this documented for fetch-pack, but not fetch.)
