No, the 10% limitation is a "threshold" and anything less than that "10% of AGI" is not allowed as a deduction in any year.
Note that "Qualified Disaster Losses" are not subject to the 10% AGI limitation. So, if your Camp Fire loss was in an area determined by the President to warrant assistance by the federal government under the Stafford Act, the 10% AGI limitation doesn't apply. If that is the case with your disaster loss, you can amend your 2018 tax return to pick up the "less than 10% amount".
