No - on the right side of the equation there are 2 H2SO4, so if the coefficient of CuSO4 was 1, there would be 1 SO4 on the left hand side and 2 SO4 on the right, so it wouldn't balance. Therefore, the coefficient of CuSO4 must be 2. And if the coefficient of CuSO4 is 2, that gives 2 Cu on the left hand side. So the coefficient of Cu on the right hand side must also be 2 to balance the equation.

Actually the problem is with the oxygen - if you start with 1 molecule of the copper sulfate, you end with half molecule of O2. By convention correctly balanced equations contains the smallest possible integer coefficients, so you have to multiply everything by two.
