Can distance_matrix be sparse matrix?

No, because the distance matrix is passed to the C++ library that does the optimization. This library doesn't support dealing with sparse matrices. You're welcome to submit a PR if this is an important feature for you, but it will be a lot of work.
Thanks for update !!
Just curious which C++ lib pyemd uses ?
See the first sentence of the README. The code is in pyemd/lib.
