Not in this case. Christian burial began with the martyr Stephen and has continued ever since. It is only recently that Christians have forgotten the meaning of Christian burial. So cremation is just for pagans, and God is not pleased when Christians adopt pagan practices.Like meat sacrificed to idols, Christmas, and others..."let each be convinced in his own mind" (Romans 14:5)
Regarding Christmas, yes originally December 25 was a pagan festival, but it has had a Christian history over many centuries. Now there you have the liberty to either disregard it or celebrate it as a Christian should.
