You may be technically correct if they are set.

In the NFL, the rules state that interior linemen cannot go in motion.
A tight end is not an interior lineman since the rules also state that
interior linemen are located between the ends.
A wide out or end can be a down lineman there just has to be 6 down
linemen. If another player moves to the line (covering the tight
end), lets say the wide-out, the end is then allowed to step back and
go into motion. That is unless another down or back is already in
motion.
Watching KC lose every weekend I see #88 in motion a lot. He'll step
to the line, wave the wide-out to the line, step back from the line,
wait for the quarterback's leg lift signal and then go into motion.
Every NFL team runs something similar.
