R5RS says that the argument to length must be a list, which means it
is an error if it is not. Implementations are not required to detect
or report errors unless the phrase "an error is signalled" is used,
which in this case it is not.
See sections 6.3.2 (length's argument must be a list), 1.3.3 (an error
for arguments to have the wrong type), 1.3.2 ("an error" need not be
detected or reported).
