Yeah, but not for multisampled framebuffers, unless RGBA8 and BGRA8
are considered identical (ARB_fbo):
If SAMPLE_BUFFERS for either the read framebuffer or
draw framebuffer is greater than zero, no copy is performed and an
INVALID_OPERATION error is generated if the dimensions of the source
and destination rectangles provided to BlitFramebuffer are not
identical, or if the formats of the read and draw framebuffers are
not identical.
