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
