Aug 27, 2013 at 16:28 comment added Tomasz Kania By a result of Lindenstrauss, the OP really asks whether $M$ is isomorphic to $\ell_\infty$.
Aug 27, 2013 at 16:25 comment added Yemon Choi The "predual" version of this question -- namely, "if a subspace of $\ell^1$ is isomorphic to $\ell^1$, is it complemented in $\ell^1$? -- has a negative answer, see J. Bourgain, A counterexample to a complementation problem, numdam.org/item?id=CM_1981__43_1_133_0 I therefore suspect that the answer to your question is negative but I'm not sure.
