In a word, no. Art Deco started to appear in the 1920s, it's a design style that makes use of geometric shapes like hexagons, trapezoids, zigzags and other sharps that incorporate sharp angles. Mirrors, rich woods, chrome and polished metals all help give Art Deco its glamorous, sophisticated look.
Art Nouveau on the other hand, started to appear much earlier than Art Deco, in the late 19th century. The style is heavily influenced by nature with ornate curves, flower, feather and insect wing designs for example. Carefully crafted metal and wood, stained glass and bas relief are typically used. Paris subway signs are arguably one of the most iconic examples of this design style.
