No.

In most cases (BSD/MIT/Apache2) the original statement has to remain, 
you can add your own (e.g. GPL statement), this is what's called 
sublicensing and is even explicitly allowed in the prototype license.

Only the copyright owner can license the code, which means you can make 
your changes GPL and thus license the whole code under the GPL, but the 
original pieces remain MIT/BSD/whatever since you cannot relicense code 
you don't have the copyright for.
