No only ETL/STL can coach TLs. You can hold your peer lead accountable though. I highly recommend doing it respectful otherwise it will be bad blood in your work relationship.
I was curious about this too many years ago and was told that a Sr during their LOD shift can direct an ETL/STL to coach the TL, but if it's on safety any TL can coach any TL.
Nobody does this though, that "bad blood" comment is spot on.
