In the short term no. If you have been riding it a lot like this then you MAY find that some of the links of the chain have deformed and the chain MAY fail. But it would need to be overly tight to where you'd feel it while riding to do this. More likely it's 100% fine. When I was first playing with SS setups I had the chain much too tight. It was fine and free running until the runouts ganged up and then it felt like I had to pedal over a "stick stuck in the chain" type of pressure that ramped up and then snapped over the top. It made for quite a cogging like feel in the pedal. If you didn't feel that sort of thing then you didn't harm the chain at all.
