Yes
mage>Rotate Canvas>Arbitrary
Note whether clockwise (CW) or couter clockwise (CCW) and type in the amount like 0.2 or whaterever.
When you do this you may need to recrop your image or clone over the canvas that is created.
You can also select the image (Ctrl A to select all) and then select the move tool. Go to just outside one of the corners and you can drag the image to rotate anyway you like.
There's other ways too - I use the crop tool. Select all with the crop tool and move the cursor to just outside one of the corner points (you'll see the cursor change to a rotate cursor). Rotate as required and press enter.
Done

You can also rotate by using the free transform tool (but this may be only useful if you have one layer or have your layers linked).
I have linked an image, which shows you the transform palette.
Basically, hit CTRL+T (Free transform), then click once in the box (see attachment) then press either the UP or DOWN keys on your keyboard. It will rotate your selection, then it's simply a matter of cropping out (or correcting) the empty space.
I used to make my rotations using the arbitrary command but I quickly got tired of going into the menu for a simple rotate.
