Not currently. It can read them, and it is used in a few drivers such as GTiff. 
Writing is done only in the MapInfo TAB driver for the vector part. The 
writing of .tab for raster files would only be a matter of implementing it...

Well, I don't know MapInfo limits with raster files. Perhaps is it just big 
raster dimensions that cause problem, or tiling, or .. ?
