Hey oh
I guess the short answer is no.
The long answer is better though.
Curry powder is usually a mix of:
Tumeric
Cloves
Chillies
Corriander sead
plus a variety of variouse other spices, some less, some more, and some powders have so much tumeric to almost be tumeric.
Here, give this a read
http://www.lionsgrip.com/curingredients.html
Curry paste, on the other hand, is an entirly different flavour, and usually has no tumeric in it, can have tomatoes in it, uses fresh corriander and fresh garlic, and fresh chillies...
NOT TO MENTION, powders are almost always Indian in essence, and pasts can be Thai or Indian, and Thai is real popular right now.
Thai currys have lemon grass, kaffir lime leaves, chillies, tamarinds, and more in them.
Hmmm
