I don't think so:
"There is a special case for a zero-length array (|N == 0|). In that
case, array.begin() == array.end(), which is some unique value. The
effect of calling front() or back() on a zero-sized array is undefined."
from https://en.cppreference.com/w/cpp/container/array
IMO this excludes nullptr as that won't be unique
