No FOX can't pull the affiliates. And I don't think they can even pressure them to pull their signal from DISH. Almost all of them are now owned by a handful of larger media corps (LIN, Sinclair etc) who each make their own contract with DISH which has to be honored until it expires. However, there are many major markets with FOX O&O's, I'll list them:
Atlanta: WAGA-TV (channel 5)
Austin, Texas: KTBC-TV (channel 7)
Boston: WFXT (channel 25)
Chicago: WFLD-TV (channel 32)
Dallas: KDFW-TV (channel 4)
Detroit: WJBK-TV (channel 2)
Houston: KRIV (channel 26)
Los Angeles: KTTV (channel 11)
Memphis: WHBQ-TV (channel 13)
Minneapolis: KMSP-TV (channel 9)
New York City: WNYW (channel 5)
Ocala, Florida: WOGX (channel 51)
Orlando: WOFL (channel 35)
Philadelphia: WTXF-TV (channel 29)
Phoenix: KSAZ-TV (channel 10)
Tampa: WTVT (channel 13)
Washington, D.C.: WTTG (channel 5)
I think thats most of the top 10 markets in the country. A very very large number of households together. If Charlie plays chicken with FOX after Nov 1 I think it will do irreparable damage to Dish Network.

To clear this up a bit......#'s 1-5, 7, 8, 10-13, 15, 19, 48, 49 and 160
This represents a majorioty of the tv households in the US.
In these abopve DMA'a there are probably close to 175 million people in residence.
Between NY, PHI, BOS and DC alone that's probably 75 to 90 milllion people.
Yep a fight between Fox and dish that involved the OTA Fox owned stations would be a bad deal fro Dish. Of course I would imagine that Dish does not have as large a presense in the NYC DMA due to the dispute between Charlie and the Steinbrenners over YES.
