Always a possibility given today's cyber forensic capabilities, but I doubt it. Filing the SAR without a suspect's name isn't required, of course, unless the check was for more than $15,000 (I'm betting it wasn't). Under that amount, there's no risk in filing, but I'd only do it if it feels good to you.
