Basically no. A student realistically should always be turning in their own work!
There is a plugin however that allows students to pick what group they want to be in and then you can set it so that the group only turns in a single assignment for the whole group (the groups need to be set up though). I guess you could set the assignment to allow multiple files and then one student could upload say five files, one named for each member of the group.
