No. UTF-7 is invalid here because it produces output that is not NUL
terminated. See:

$ printf 'ab\0' | iconv -t UTF-7 | od -t c
0000000   a   b   +   A   A   A   -
0000007

strlen() on such a return value makes invalid memory accesses.
You can convince yourself by running
$ OUTPUT_CHARSET=UTF-7 valgrind ls --help
