Dear Magnus.
you can iterate through the layers:
for lay in QgsMapLayerRegistry.instance().mapLayers().values():
if lay.name() == your_layer_name:
your layer is loaded

I'm writing a plugin that adds feature to a SHP-layer, specified as a filename.
If the layer already is loaded in Qgis, I want to check for and use the loaded
layer instead of creating a new from the same SHP-file.
Is this even possible?
