No, these are likely fragments from other trilobites carved to look like antennae. Features like legs and antennae very rarely fossilize, and usually only in Konservat-Lagsteratte sites. When antennae are present, they would be much thinner. 

 

This appears to be an Asaphellus sp. from Morocco.

 

To give you an idea, here is an example of soft-body preservation. This is from the Beecher beds in NY of a Triarthrus:

If you are interested in acquiring Lagerstatte material from Morocco, here is a good introductory paper on the Fezouata biota:

 

Van Roy, P., Briggs, D.E.G., and R R. Gaines (2015) The Fezouata fossils of Morocco; an extraordinary record of marine life in the Early Ordovician. Journal of the Geological Society 7: 541-549  LINK

 

Given the pygidial spine on this one, it may not be Asaphellus, but more likely a Megistaspis hammondi
