29er tubes and 700c tyres

This is probably a stupid question, but, can I use a 29" x 1.9/2.125 tube in a 700c x 35mm tyre?

Thanks in advance.

It maybe a tad thick and cause creasing, which can lead to punctures.
Tubes suitable for hybrid tyres, 700 x 28/35 will work much better.
If your question was, are 700c and 29" the same diametre? The answer is yes.
I use road rims (open Pro) on my 29er with 29 tyres up to 2.25.
