Not a Code violation unless exposed to physical damage.
Also refer to Section 250.118(6) Lengths over six feet MUST have a grounding conductor.

If it was easy, anyone could do it.

Always run a grounded conductor.
Just having a discussion with my leadman and he thinks we should run EMT in walls. Without ripping away walls Flex should be legal to run. He swears that in our enviroment flex shouldnt be used. I cant find anything that says we cant.

EMT (Thinwall) is allowed to be fished without couplings.

Quote

358.30(A)

Exception No. 2: For concealed work in finished buildings or prefinished wall panels where such securing is impracticable,
unbroken lengths (without coupling) of EMT shall be permitted to be fished.
