No I don't think so. According to Apples website (https://support.apple.com/en-us/HT211238) the earliest supported iMac is the mid 2014 version.

FWIW, a 2014 Mac is an "older Mac". As is a 2015, 2016, 2017, 2018 and 2019 Mac. Unfortunately a 2013 iMac doesn't have the hardware to support Big Sur. But, it can run Catalina which is only a year old.
