Yes, but only if that GFCI circuit supplies power to that one bathroom, and to nothing outside that one bathroom. Reference 210.11(C)(3).

{Edit: Looks like George beat me to the draw. Must have been while I was looking up the reference.}

Take a look at 210.11(C)(3). The circuit has to be 20 amp. But you make me wonder if this is a new construction project or an upgrade to an existing house.

Being that you are only adding this light to the load side of an existing 15 amp GFCI circuit or receptacle, which we will assume was per code when the original wiring was done, IMO you are fine.

Actually you do not need to wire it to the load side if you are dealing with a receptacle.

If possable keep it on line side.Should it trip you are putting them in the dark.Years ago it was common to wire 2 bedroom and a bath on one 15 amp circuit.I am sure we are not liked today over this.

shadow,

There might be local ordinance for existing buildings that you will need to satisfy. Your inspector will have the answer.

In my area, there is the general understanding that an existing 15 amp circuit can be used to install a receptacle in an existing bathroom only when the work occurring in the bath is minimal.

If the plumbing is being reworked or replaced, opening the access to the waste stack, the guidelines require the running of a new 20 Amp circuit.

Also, if 50%, or more, of the wall area is opened as part of the reset of the bath, the room must be upgraded to current NEC standard.

As I understand the thinking, when a room is being remodeled, the related work makes access to wiring routes the best that they are likely ever to be short of a total gut to studs. The price to improve the wiring, while high, will still be as low as it will ever be, and, is most likely to be a small portion of the budget for the entire bath reset.
