No you can't fix it in Lightroom. Capture One Pro does have a feature that supposedly fixes it but I haven't tried it. I get moiré very often and fix it in Photoshop. It's a tedious process as you have to go over the image at 100% magnification and paint out the moiré with the brush tool, but the following technique works very well (thanks to Patrick Lavoie on Photo.net):

 

1. duplicate the background

 

2. apply a strong Gaussian blur, one where you still see some silhouette but barely, in the range of 15-20.

3. add a small amount of Noise on top of this new blurred image, around 3-5, Gaussian, monochromatic.

4. change the Blending Mode of this layer from Normal to Color

5. create a mask, fill with black, use a brush with white paint to remove the moiré effect.

 

On the rare occasions when this doesn't work because color from an adjacent area bleeds into the area you're brushing over, you can create a mask of the area with moiré, add a new layer, and paint over it in that layer.
