Can you use 10g SR SFPs with SMF patch cables or short runs (less than 100ft)?

I ask because I got a new 9300 and a stack of 2960xs with 10g SR SFPs on both ends and the link is up using SMF patch cables. Granted this with them sitting right next to each other but I just assumed the link wouldn't come up at all.
