In relation to editing Tables, reordering, remaning etc.. can be carried out 
using Refactor fields, which can be found in the Processing Toolbox

There should be a method renameAttribute as part of QgsVectorLayer class.

You can do something like that:

layer = iface.activeLayer()
for field in layer.pendingFields():
if field.name() == 'old':
with edit(layer):
idx = layer.fieldNameIndex(field.name())
layer.renameAttribute(idx, 'new')

Good luck!

Hello,
I have a little problem with the field calculator. I want to rename a column, 
and I don´t find any way to do it.
Now I tried to copy the field values in a new column with the right name, and 
am also not successful. Has anybody an idea for me, how to solve the problem? 
Many thanks in advance!
Ursula Heinze

[Ujaval Gandhi]

You can also use the 'Refactor Fields' algorithm from the Processing
Toolbox - which can not only rename the fields but also change the order
and types as well.

Re: [Qgis-user] Rename column

[Matt Boyd]

You can rename columns (or fields) in the layer properties (need to
have editting turned on)
In the field calculator, sometimes I have issues with the data type
and "fieldname" doesn't work so well but if I do "1*fieldname" it
does.
