You could also use a ternary (inline if/else) statement. It might look like this:

row = this.props.cells.map(function(cell, i) {
    return (cell.URL != null && cell.URL.length > 0) ? 
        ({cell.Text}) :
        ({cell.Text})
}.bind(this));

or es6

row = this.props.cells.map((cell, i) => (cell.URL != null && cell.URL.length > 0) ? 
        ({cell.Text}) :
        ({cell.Text})
);

but, for readability, I would suggest nilgun's answer.

Although I would remove the else statement, since it is redundant. You could also remove the curly brackets, this is a matter of preference.

row = this.props.cells.map(function(cell, i) {
    if(cell.URL != null && cell.URL.length > 0)
        return {cell.Text};        
    return {cell.Text};
}.bind(this));
